The conductive wire harness 17 is divided into two groups, one group is fixedly connected to the left end of the casing 1, and the other group is fixedly connected to the right end of the casing 1. , the right conducting wire bundle 17 has two branches, the upper branch is electrically connected to the sinoatrial node, and the lower branch is electrically connected to the atrial myocardium. Compared with the pacemaker pulse current through the spontaneous beating biocurrent of the sinoatrial node, in the When the heart beats spontaneously and normally, the pacemaker is disconnected, the right side of the middle of the housing 1 is rotatably connected with a turntable 18, the periphery of the turntable 18 is fixedly connected with a magnetic ring 19, and the outside of the axis of the turntable 18 is fixedly connected with a rotating rod 20.

When the blood pressure inside the atrium rises, the adventitia 2 is compressed to the inside of the shell 1, and the air tightness between the adventitia 2 and the intima 4 is good. With the amplifying effect of the intima 4, the movable block 5 is moved toward the center of the fixed frame 9. Moving, the left and right ends of the movable block 5 are hinged with the connecting rod 1 6. Based on the transmission of the connecting rod 1 6, the pressure block 7 is moved inside the air cavity 10. The air cavity 10 has good air tightness, and the movable block 5 is pressed down. The pressure blocks 7 on the left and right sides are moved to the inner walls of the left and right sides of the casing 1 respectively. At this time, the air pressure inside the air cavity 10 increases, and the plug bodies 11 are far away from each other, reducing the facing area between the capacitor plates 12. According to the formula: C=εS/4πkd, the reduction of the facing area S reduces the capacitance C, which increases the charging and discharging frequency of the capacitor plate 12, that is, the pulse current discharging frequency is increased. The inner wall moves, driving the contact two 21 to reduce the resistance value of the access amplitude modulation resistor 16, increasing the intensity of the pulse current, to achieve the effect of adjusting the pacing frequency according to the intra-atrial blood pressure, to prevent excessive fluid accumulation in the atrial from compressing the ventricular diastole, A turntable 18 is rotatably connected to the right end of the fixed frame 9 , a magnetic ring 19 is fixedly connected to the periphery of the turntable 18 , and the conductive wire bundle 17 is electrically connected to the sinus node and the atrial myocardium, respectively.

When the patient's heart rate is too slow, when the frequency of the current generated by the sinus node is weaker than the set pacing current frequency, the upper electromagnet 23 is energized at a low frequency. At the energization frequency of the electromagnet 23 on the lower side, due to the imbalance of the magnetic field on the upper and lower sides, the magnetic ring 19 drives the rotating rod 20 to rotate, so that the contact two 21 is rotated to communicate with the inner wall of the communication ring 22, and the pacemaker is connected to work, thereby reaching the patient's heart rate. The effect of automatically turning off the pacemaker in normal conditions prevents the patient from becoming dependent on pacing.

Moving, the first plug body 11 is far away from each other, reducing the facing area between the capacitor plates 12, increasing the charging and discharging frequency of the capacitor plate 12, and changing the pulse current discharge frequency. The second contact 21 reduces the resistance value of the connected amplitude modulation resistor 16 and increases the intensity of the pulse current, thereby achieving the effect of adjusting the pacing frequency according to the intra-atrial blood pressure and preventing excessive fluid accumulation in the atrium from compressing the ventricular diastole.
