技术领域Technical Field

本申请涉及一种心电数据分析方法、装置、计算机设备与存储介质。The present application relates to an electrocardiogram data analysis method, apparatus, computer equipment and storage medium.

背景技术Background Art

通过对心脏病的预防、监测与及时康复治疗，能够有效降低心脏病致死率。而在心脏病的第一阶段如何评估心脏康复情况，以便于医生基于心脏康复情况与临床症状提供进一步地康复指导参考建议。The prevention, monitoring and timely rehabilitation of heart disease can effectively reduce the mortality rate of heart disease. In the first stage of heart disease, how to evaluate cardiac rehabilitation can help doctors provide further rehabilitation guidance and reference suggestions based on cardiac rehabilitation and clinical symptoms.

目前，通常基于临床金标准或心电图中ST-T段数据来评估心脏康复情况，但是多数临床金标准是有创检测，会对受测者的身体健康产生或多或少的影响，而基于ST-T段数据通过模糊的定性来识别受测者的心脏健康状况，从而评估心脏康复情况，存在评估准确性低的问题。由此可见，现有评估方式存在无创无损与准确性不能兼顾的问题。At present, cardiac rehabilitation is usually evaluated based on clinical gold standards or ST-T segment data in electrocardiograms. However, most clinical gold standards are invasive tests, which will have more or less impact on the physical health of the subjects. Based on ST-T segment data, the heart health status of the subjects is identified through fuzzy qualitative analysis, and thus the cardiac rehabilitation status is evaluated, which has the problem of low evaluation accuracy. It can be seen that the existing evaluation methods have the problem of not being both non-invasive and non-destructive and being accurate.

The clinical indications of the subject before the rehabilitation stage are used to indicate the ECG test applicable to the subject before the rehabilitation stage, and are specifically used to indicate whether the subject can undergo a stress exercise ECG test, including clinical data such as whether the subject is hypoglycemic, hypotensive, and in the acute stage of myocardial infarction, and whether the vital signs are stable. If the vital signs are stable and hypoglycemia, hypotension, and acute stage of myocardial infarction are excluded, indicating that the subject can undergo a stress exercise ECG test, then the target ECG test that matches the clinical indication includes a resting ECG test and a stress exercise ECG test. Otherwise, indicating that the subject cannot undergo a stress exercise ECG test, then the target ECG test that matches the clinical indication includes a resting ECG test. The subject is in a resting state during the resting ECG test. The subject is in an exercise state during the stress exercise ECG test to increase the subject's cardiac load through exercise. The specific contents of the above clinical indications are only examples and are not intended to be specific limitations.

具体地，获取受测者的当前心电数据，该当前心电数据是在第一阶段的目标心电检测过程中采集到的心电数据，该目标心电检测由该受测者在第二阶段的临床适应症确定。目标心电检测至少包括静息心电检测，当前心电数据至少包括在第一阶段的静息心电检测过程中采集到的当前静息心电信号。Specifically, the current ECG data of the subject is obtained, and the current ECG data is the ECG data collected during the target ECG detection process of the first stage, and the target ECG detection is determined by the clinical indication of the subject in the second stage. The target ECG detection at least includes a resting ECG detection, and the current ECG data at least includes a current resting ECG signal collected during the resting ECG detection process of the first stage.

当前整体风险评估分数用于表征心脏当前出现问题的整体风险大小，如当前整体风险评估分数越高，表征心脏当前出现问题的整体风险越大，也即是表征在第一阶段心脏出现问题的整体风险越大。The current overall risk assessment score is used to characterize the overall risk of the current heart problem. For example, the higher the current overall risk assessment score is, the greater the overall risk of the current heart problem is, which means that the overall risk of the heart problem in the first stage is greater.

具体地，按照目标心电检测对当前心电数据中QRS波群的高频成分进行分析得到当前参考特征，并根据当前参考特征确定当前整体风险评估分数。当前心电数据中包括多个反映左、右心室除极电位和时间的变化的QRS波群，每个QRS波群包括高频成分与低频成分。通过分别对每个目标心电检测对应的当前心电数据中QRS波群的高频成分进行分析，得到该目标心电检测所对应的当前参考特征。对所得到的当前参考特征进行综合分析得到当前整体风险评估分数。Specifically, the high-frequency components of the QRS complex in the current ECG data are analyzed according to the target ECG detection to obtain the current reference features, and the current overall risk assessment score is determined based on the current reference features.

在其中一个实施例中，按照目标心电检测将当前参考特征输入相应预设的风险评估函数或预先训练好的风险评估模型，得到当前整体风险评估子分数，并根据各当前整体风险评估子分数确定当前整体风险评估分数。In one of the embodiments, the current reference features are input into a corresponding preset risk assessment function or a pre-trained risk assessment model according to the target ECG detection to obtain the current overall risk assessment sub-scores, and the current overall risk assessment score is determined based on the current overall risk assessment sub-scores.

自律神经支配评估分数用于表征自律神经支配异常的风险大小，如自律神经支配评估分数越高，表征自律神经支配异常的风险越大。心功能评估分数与心功能等级相关，心功能评估分数越高，心功能等级越高，表征心脏的功能下降越多。The autonomic nerve control assessment score is used to characterize the risk of autonomic nerve control abnormality. For example, the higher the autonomic nerve control assessment score, the greater the risk of autonomic nerve control abnormality. The cardiac function assessment score is related to the cardiac function grade. The higher the cardiac function assessment score, the higher the cardiac function grade, and the greater the decline in cardiac function.

具体地，对当前静息心电信号中QRS波群的高频成分进行分析得到当前高频QRS包络曲线，分析当前高频QRS包络曲线得到自律神经支配评估分数与心功能评估分数。Specifically, the high-frequency components of the QRS wave group in the current resting electrocardiogram signal are analyzed to obtain the current high-frequency QRS envelope curve, and the current high-frequency QRS envelope curve is analyzed to obtain the autonomic nerve control assessment score and the cardiac function assessment score.

For example, the higher the historical overall risk assessment score is, the greater the overall risk of having heart problems in the second stage.

具体地，获取受测者的历史整体风险评估分数，该历史整体风险评估分数是基于受测者的历史心电数据确定的，该历史心电数据是在第二阶段的目标心电检测过程中采集到的心电数据，该目标心电检测由该受测者在第二阶段的临床适应症确定。目标心电检测至少包括静息心电检测，历史心电数据至少包括在第二阶段的静息心电检测过程中采集到的历史静息心电信号。可以理解，参照本申请的一个或多个实施例中基于当前心电数据确定当前整体风险评估分数的处理流程，基于历史心电数据确定历史整体风险评估分数，在此不再赘述。Specifically, the historical overall risk assessment score of the subject is obtained, and the historical overall risk assessment score is determined based on the historical ECG data of the subject, and the historical ECG data is the ECG data collected during the target ECG detection process in the second stage, and the target ECG detection is determined by the clinical indication of the subject in the second stage.

整体风险变化指标用于表征心脏出现问题的整体风险的变化情况，以便于医生结合康复前后的临床症状准确评估受测者的心脏康复效果。例如，若整体风险变化指标为负数，则表征心脏出现问题的整体风险增加，且整体风险变化指标的绝对值越大，表征该整体风险增加得越多，表征存在心脏康复效果越差的可能性，若整体风险变化指标为正数，则表征心脏出现问题的整体风险下降，则整体风险变化指标越大，表征该整体风险下降得越多，表征存在心脏康复效果越好的可能性，若整体风险变化指标为0，则表征心脏出现问题的整体风险持平，表征存在心脏康复无效果的可能性。目标风险评估等级也可理解为心脏风险评估等级，用于表征在第一阶段心脏出现问题的风险大小，如目标风险评估等级越高，表征在第一阶段心脏出现问题的风险越大，以便于医生结合整体风险变化指标与临床症状准确识别受测者的心脏康复情况，从而给出进一步地康复指导参考建议。The overall risk change index is used to characterize the change in the overall risk of heart problems, so that doctors can accurately evaluate the cardiac rehabilitation effect of the subject in combination with the clinical symptoms before and after rehabilitation. For example, if the overall risk change index is a negative number, it indicates that the overall risk of heart problems has increased, and the larger the absolute value of the overall risk change index, the more the overall risk has increased, indicating the possibility of a worse cardiac rehabilitation effect. If the overall risk change index is a positive number, it indicates that the overall risk of heart problems has decreased. The larger the overall risk change index, the more the overall risk has decreased, indicating the possibility of a better cardiac rehabilitation effect. If the overall risk change index is 0, it indicates that the overall risk of heart problems remains the same, indicating the possibility of no effect of cardiac rehabilitation. The target risk assessment level can also be understood as the cardiac risk assessment level, which is used to characterize the risk of heart problems in the first stage. For example, the higher the target risk assessment level, the greater the risk of heart problems in the first stage, so that doctors can accurately identify the cardiac rehabilitation status of the subject in combination with the overall risk change index and clinical symptoms, and thus provide further rehabilitation guidance reference suggestions.

具体地，根据当前整体风险评估分数与历史整体风险评估分数确定整体风险变化指标，并根据当前整体风险评估分数、自律神经支配评估分数与心功能评估分数确定目标风险评估等级。Specifically, the overall risk change index is determined based on the current overall risk assessment score and the historical overall risk assessment score, and the target risk assessment level is determined based on the current overall risk assessment score, the autonomic nervous system innervation assessment score and the cardiac function assessment score.

Specifically, the average voltage of the limb leads is determined according to the current high-frequency QRS envelope curve corresponding to each limb lead, and the average voltage of the chest leads is determined according to the current high-frequency QRS envelope curve corresponding to each chest lead. The ratio of the average voltage of the limb leads to the average voltage of the chest leads is input into a preset autonomic nerve dominance assessment function to obtain an autonomic nerve dominance assessment score.

在其中一个实施例中，预设的自律神经支配评估函数的表达式如下：In one embodiment, the expression of the preset autonomic nerve control evaluation function is as follows:

其中， 表示自律神经支配评估分数， 表示肢体导联平均电压与胸导联平均电压的比值。 in, represents the autonomic nervous system assessment score, It represents the ratio of the average voltage of the limb leads to the average voltage of the chest leads.

在其中一个实施例中，心功能评估指标包括QRS时限与各静息导联对应的当前高频形态指数；根据心功能评估指标确定心功能评估分数，包括：根据QRS时限确定系数，根据当前高频形态指数确定相应静息导联的分值；根据各分值的和值与系数的乘积确定心功能评估分数。In one embodiment, the cardiac function assessment index includes the QRS duration and the current high-frequency morphology index corresponding to each resting lead; the cardiac function assessment score is determined according to the cardiac function assessment index, including: determining the coefficient according to the QRS duration, determining the score of the corresponding resting lead according to the current high-frequency morphology index; and determining the cardiac function assessment score according to the product of the sum of the scores and the coefficient.

QRS时限是自QRS波群起点至QRS波群终点的持续时长，QRS时限的延长与传导阻滞有关。具体地，通过分析各静息导联对应的当前高频QRS包络曲线，得到QRS时限与各静息导联对应的当前高频形态指数。将每个静息导联的当前高频形态指数与各预设指数区间进行匹配，以确定相应静息导联的分值，将QRS时限与各预设时限区间进行匹配，以确定系数，对各静息导联的分值求和，将各静息导联分值的和值与系数相乘得到总得分，并根据该总得分确定心功能评估分数。各预设指数区间与分值相关联，各预设时限区间与系数相关联。可以理解，心功能评估分数与心功能分级相关，心功能评估分数越高，对应心功能分级的级别越高，表征心脏的功能下降越多。The QRS duration is the duration from the start of the QRS complex to the end of the QRS complex, and the extension of the QRS duration is related to conduction block. Specifically, by analyzing the current high-frequency QRS envelope curve corresponding to each resting lead, the QRS duration and the current high-frequency morphological index corresponding to each resting lead are obtained. The current high-frequency morphological index of each resting lead is matched with each preset index interval to determine the score of the corresponding resting lead, the QRS duration is matched with each preset time limit interval to determine the coefficient, the score of each resting lead is summed, and the sum of the scores of each resting lead is multiplied by the coefficient to obtain a total score, and the cardiac function assessment score is determined according to the total score. Each preset index interval is associated with a score, and each preset time limit interval is associated with a coefficient. It can be understood that the cardiac function assessment score is related to the cardiac function grade. The higher the cardiac function assessment score, the higher the level of the corresponding cardiac function grade, and the more the heart function declines.

举例说明，预设指数区间包括[10%，19.9%]、[20%，29.9%]、[30%，39.9%]、[40%，49.9%]与[50%，100%]，该五个区间各自对应的分值分别为1，2，3，4与5，若当前高频形态指数处于[10%，19.9%]，则相应静息导联的分值为1，以此类推。可以理解，在该示例中，若当前高频形态指数小于10%，则相应静息导联的分值为0。预设时限区间包括[0，119]、[120，149]，以及大于或等于150，单位为ms（毫秒），该三个预设时限区间各自对应的系数分别为1、1.25与1.5。For example, the preset index intervals include [10%, 19.9%], [20%, 29.9%], [30%, 39.9%], [40%, 49.9%] and [50%, 100%], and the scores corresponding to the five intervals are 1, 2, 3, 4 and 5 respectively. If the current high-frequency morphology index is at [10%, 19.9%], the score of the corresponding resting lead is 1, and so on. It can be understood that in this example, if the current high-frequency morphology index is less than 10%, the score of the corresponding resting lead is 0. The preset time limit intervals include [0, 119], [120, 149], and greater than or equal to 150, in ms (milliseconds), and the coefficients corresponding to the three preset time limit intervals are 1, 1.25 and 1.5 respectively.

在其中一个实施例中，在基于QRS时限与各当前高频形态指数得到总得分后，将该总得分与第一权重的乘积作为心功能评估分数，或者，将该总得分输入预设的心功能评估函数得到相应心功能评估分数。第一权重可自定义，比如0.25。心功能评估函数的表达式如下：In one embodiment, after obtaining a total score based on the QRS duration and each current high frequency morphology index, the product of the total score and the first weight is used as the cardiac function evaluation score, or the total score is input into a preset cardiac function evaluation function to obtain a corresponding cardiac function evaluation score. The first weight can be customized, such as 0.25. The expression of the cardiac function evaluation function is as follows:

The lead positive index indicates positive, which is used to characterize that the current high-frequency morphology index of the corresponding resting lead is greater than or equal to the second index threshold, and the age of the subject is greater than or equal to the preset age, or it is used to characterize that the current high-frequency morphology index of the corresponding resting lead is greater than or equal to the third index threshold, and the age of the subject is less than the preset age. The second index threshold and the third index threshold can be customized, for example, the second index threshold is 8% and the third index threshold is 15%. The preset age can be customized, for example, 50 years old. The arrhythmia assessment index is used to characterize whether the subject has the possibility of arrhythmia, and is specifically used to characterize whether arrhythmia occurs in the low-frequency electrocardiogram.

具体地，将各静息导联分值的和值与系数的乘积作为总得分，并根据该总得分确定第一心功能评估子分数。根据各当前高频QRS包络曲线确定相应静息导联的导联阳性指标，筛选并统计导联阳性指标指示为阳性的静息导联得到当前静息阳性导联数量，并根据当前静息阳性导联数量确定第二心功能评估子分数。分析当前静息心电信号得到低频心电图，分析该低频心电图得到心律失常评估指标，并根据心律失常评估指标确定第三心功能评估子分数。具体可参照现有技术，基于当前静息心电信号分析相应低频心电图中是否出现心律失常，在此不再赘述。进一步地，根据第二心功能评估子分数与第三心功能评估子分数中的至少一项，以及第一心功能评估子分数确定心功能评估子分数。可将上述总得分、当前静息阳性导联数量与心律失常评估指标，分别输入相应心功能评估子函数得到相应心功能评估子分数。Specifically, the sum of the scores of each resting lead and the product of the coefficient are taken as the total score, and the first cardiac function assessment sub-score is determined based on the total score.

The second cardiac function assessment sub-score is determined by the current number of resting positive leads and the current number of resting critical leads. The current number of resting critical leads refers to the number of resting leads for which the corresponding lead positive index indicates critical, which can be used to assess the critical risk of myocardial ischemia in the resting state in the first stage.

The current exercise ECG signal is divided into multiple ECG signal subsets according to the timing and the preset moving step size through a window function, and each ECG signal subset includes QRS wave groups corresponding to multiple heartbeats. For each ECG signal subset, the QRS wave groups corresponding to the multiple heartbeats included therein are aligned, averaged and high-frequency filtered in turn to obtain the corresponding high-frequency QRS wave group data (high-frequency band data of the QRS wave group), and the high-frequency QRS wave group data is root-mean-squared to obtain the corresponding root-mean-square voltage, which is used as the root-mean-square voltage/intensity/amplitude corresponding to the ECG signal subset.

The current exercise reference feature is input into the risk assessment function or risk assessment model preconfigured for load exercise ECG detection to obtain the second current overall risk assessment sub-score.

The maximum value among the first current overall risk assessment sub-score, the second current overall risk assessment sub-score and the third current overall risk assessment sub-score is determined as the current overall risk assessment score.

在其中一个实施例中，针对静息心电检测与负荷运动心电检测联合配置的风险评估函数的表达式，如下：In one embodiment, the expression of the risk assessment function for the joint configuration of resting ECG detection and stress exercise ECG detection is as follows:

其中， 为第三当前整体风险评估子分数， 为当前静息临界导联数量， 为当前静息阳性导联数量， 为第一目标导联数量， 为基于当前目标高频形态指数确定的附加分数， 为当前运动临界导联数量， 为当前运动阳性导联数量， 为基于各运动导联对应的第二振幅下降相对值确定的附加分数。 in, The third current overall risk assessment sub-score is is the current number of resting critical leads, is the current number of resting positive leads, is the first target lead number, is an additional score determined based on the current target high frequency morphology index, is the current number of critical motion leads, is the current number of motion-positive leads, It is an additional score determined based on the relative value of the second amplitude decrease corresponding to each motion lead.

在其中一个实施例中，基于当前心电数据确定当前整体风险评估分数的表达式，还可表示如下：In one embodiment, the expression for determining the current overall risk assessment score based on the current ECG data can also be expressed as follows:

其中， 为当前整体风险评估分数， 为第一当前整体风险评估子分数， 为第二当前整体风险评估子分数， 为第三当前整体风险评估子分数。 in, is the current overall risk assessment score, is the first current overall risk assessment sub-score, is the second current overall risk assessment sub-score, is the third current overall risk assessment sub-score.

上述实施例中，在当前静息参考特征与当前运动参考特征基础上，还结合由当前静息心电信号与当前运动心电信号联合确定的当前融合参考特征，更准确地评估当前整体风险评估分数，以进一步得到更准确地康复指导参考指标供医生参考，以便于医生结合临床症状更准确地识别受测者在第一阶段的心脏康复情况，从而给出进一步康复指导参考建议。In the above embodiment, based on the current resting reference features and the current motion reference features, the current fusion reference features jointly determined by the current resting ECG signal and the current motion ECG signal are combined to more accurately evaluate the current overall risk assessment score, so as to further obtain more accurate rehabilitation guidance reference indicators for doctors' reference, so that doctors can more accurately identify the subject's cardiac rehabilitation status in the first stage in combination with clinical symptoms, and thus give further rehabilitation guidance reference suggestions.

在其中一个实施例中，S110包括：根据当前整体风险评估分数与历史整体风险评估分数确定整体风险变化指标；根据当前整体风险评估分数、自律神经支配评估分数与心功能评估分数确定目标风险评估等级。In one embodiment, S110 includes: determining an overall risk change index based on a current overall risk assessment score and a historical overall risk assessment score; and determining a target risk assessment level based on a current overall risk assessment score, an autonomic nervous system innervation assessment score, and a cardiac function assessment score.

具体地，将历史整体风险评估分数减去当前整体风险评估分数得到的分数差值作为整体风险变化指标，或者，将历史整体风险评估分数、当前整体风险评估分数分别与各预设分数区间进行比较，得到历史整体风险评估等级与当前整体风险评估等级，将历史整体风险评估等级减去当前整体风险评估等级得到等级差值，将该等级差值与第二权重的乘积确定为整体风险变化指标。将当前整体风险评估分数与第三权重的乘积，以及自律神经支配评估分数与心功能评估分数求和得到目标风险评估分数，并将目标风险评估分数与各预设分数区间进行比较得到目标风险评估等级。第二权重与第三权重可自定义，比如第二权重为10，第三权重为0.5。Specifically, the score difference obtained by subtracting the current overall risk assessment score from the historical overall risk assessment score is used as the overall risk change indicator, or the historical overall risk assessment score and the current overall risk assessment score are compared with each preset score interval to obtain the historical overall risk assessment level and the current overall risk assessment level, and the level difference is obtained by subtracting the current overall risk assessment level from the historical overall risk assessment level, and the product of the level difference and the second weight is determined as the overall risk change indicator. The product of the current overall risk assessment score and the third weight, and the sum of the autonomic nerve control assessment score and the cardiac function assessment score are obtained to obtain the target risk assessment score, and the target risk assessment score is compared with each preset score interval to obtain the target risk assessment level. The second weight and the third weight can be customized, for example, the second weight is 10 and the third weight is 0.5.

举例说明，以整体风险评估等级（包括历史整体风险评估等级与当前整体风险评估等级）与目标风险评估等级均包括依次升高的第一等级至第六等级共六个等级为例，针对每个等级预配置有相应的预设分数区间，分别为[0,10]、[11,30]、[31,50]、[51,60]、[61,70]、大于或等于71，该六个预设分数区间分别与整体风险评估等级或目标风险评估等级对应，若历史整体风险评估分数为80，且当前整体风险评估分数为46，则可将整体风险变化指标确定为34，或者，将历史整体风险评估等级确定为第六等级，将当前整体风险评估等级确定为第三等级，则将整体风险变化指标确定为3*10=30。若自律神经支配评估分数为30，心功能评估分数为10，则目标风险评估分数为46*0.5+30+10=63，则将目标风险评估等级确定为第五等级。可以理解，针对整体风险评估等级与目标风险评估等级划分的等级数量与预配置的预设分数区间均可不同。For example, the overall risk assessment level (including the historical overall risk assessment level and the current overall risk assessment level) and the target risk assessment level both include six levels from the first level to the sixth level in ascending order. For each level, a corresponding preset score interval is pre-configured, which is [0,10], [11,30], [31,50], [51,60], [61,70], and greater than or equal to 71. The six preset score intervals correspond to the overall risk assessment level or the target risk assessment level, respectively. If the historical overall risk assessment score is 80 and the current overall risk assessment score is 46, the overall risk change index can be determined as 34, or the historical overall risk assessment level is determined as the sixth level and the current overall risk assessment level is determined as the third level, then the overall risk change index is determined as 3*10=30. If the autonomic nerve control assessment score is 30 and the cardiac function assessment score is 10, then the target risk assessment score is 46*0.5+30+10=63, and the target risk assessment level is determined as the fifth level. It can be understood that the number of levels and the pre-configured preset score ranges for the overall risk assessment level and the target risk assessment level may be different.

上述实施例中，基于第一阶段的当前整体风险评估分数与第二阶段的历史整体风险评估分数，得到表征整体风险变化情况的整体风险变化指标，基于由第一阶段的当前心电数据得到的当前整体风险评估分数、自律神经支配评估分数与心功能评估分数，得到表征受测者在第一阶段心脏出现问题的风险大小的目标风险评估等级，以供医生参考，以便于医生结合临床症状准确识别受测者在第一阶段的心脏康复情况，从而给出进一步的康复指导参考建议。In the above embodiment, based on the current overall risk assessment score of the first stage and the historical overall risk assessment score of the second stage, an overall risk change index characterizing the overall risk change is obtained, and based on the current overall risk assessment score, the autonomic nervous system control assessment score and the cardiac function assessment score obtained from the current electrocardiogram data of the first stage, a target risk assessment level characterizing the risk of the subject having heart problems in the first stage is obtained for the doctor's reference, so that the doctor can accurately identify the subject's cardiac rehabilitation status in the first stage in combination with the clinical symptoms, and thus provide further reference suggestions for rehabilitation guidance.
