Cardiac pace-making system and medical apparatus for treating arrhythmia

The invention provides a cardiac pace-making system and a medical apparatus for treating the arrhythmia. The logic and time sequence part of the pace-making function is provided by the firmware of a microprocessor. The function of sensing and distributing pulses is provided by a peripheral integrated circuit. The microprocessor and the peripheral integrated circuit are communicated through a serial interface and a level signal. In this way, the internal resource of a modern ultralow-power-consumption microprocessor is fully utilized. Meanwhile, the dependence of the system on the peripheral integrated circuit is reduced. The design workload of a digital circuit is reduced. Moreover, the time of the heart atrioventricular in sensing and pace making is recorded inside a pacemaker. The problem in the prior art that the time of the heart atrioventricular in sensing and pace making is distorted due to the transmission delay during the corresponding time recording process of a program control instrument can be solved.
