Background technique

At present, with the improvement of people's living standards and the acceleration of the pace of life, the incidence of cardiovascular diseases has risen rapidly, which has become one of the main factors threatening human health. The electrocardiogram is the main basis for the treatment of such diseases. It has the advantages of reliable diagnosis, simple method and no harm to patients. The conventional electrocardiogram is the electrocardiographic activity recorded by the electrocardiograph when the patient is lying still. It lasts only a dozen seconds to one minute and can only obtain a small amount of information about the state of the heart. Real-time monitoring and recording of the patient's ECG data, so it has a fast ECG monitor that is easy to use and can be carried around, and it is automatically stored. The gradual development of mobile medical equipment provides opportunities for the above goals. Some of the existing ECG detection devices are a single device, and some communicate with smart phones through wireless modules, but these devices require special equipment. Wireless Bluetooth has increased Equipment cost, no ECG data transmission through the existing audio interface or USB interface of the smart phone.

To sum up, it is necessary to design a portable full-lead ECG detection device based on the audio interface of the smart phone or the USB interface to solve the above problems.
