Abstract

The invention provides a cardiac pace making system which comprises a perception module, a pace making module and a control module. Under a normal atrioventricular conduction condition, the control module controls the cardiac pace making system to work in a first mode and detect whether atrioventricular block occurs; various atrioventricular block events can be judged accurately by sensing and comparing PR (punctum remotum) intervals and ventricular event missing; when the atrioventricular block occurs, the control module controls the cardiac pace making system to work in a second mode; and acardiac pacemaker can timely work in an appropriate mode and provide an appropriate AV (atrioventricular) time sequence and a ventricular rhythm.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cardiac pacing system. Background technique [0002] Cardiac pacemaker (cardiac pacemaker) is an electronic therapy device implanted in the body. It sends out electric pulses powered by batteries through the pulse generator, and stimulates the myocardium contacted by the electrodes through the conduction of the wire electrodes to make the heart excited and contracted. , so as to achieve the purpose of treating cardiac dysfunction caused by certain arrhythmias. Cardiac pacemakers can generally be divided into single-chamber pacemakers and dual-chamber pacemakers. Single-chamber pacemakers sense and / or pace the atria or ventricles. Among them, the AAI mode of the traditional pacemaker can only provide the basic timing of the atrium, which is suitable for patients with sinoatrial node / atrial dysfunction. However, for patients with AVB (Atria Ventricular Block, atrioventricular bl...
