Abstract

The invention provides a cardiac pacemaker which comprises a control module and a perception module. The cardiac pacemaker can be switched into second modes to work during atria ventricular block, atria ventricular conduction recovery can be simultaneously detected by the perception module under the control of the control module by means of AV (atria ventricular) conduction section search according to preset periods, the cardiac pacemaker can be switched into first modes to work when atria ventricular conduction recovery is detected by the perception module, the preset periods include C waiting intervals which are sequentially arranged, a waiting interval is available after each section of AV conduction section search, each later waiting interval is not shorter than the corresponding previous waiting interval, and the last waiting interval in the preset periods is longer than the first waiting interval. Compared with existing cardiac pacemakers, the cardiac pacemaker in the configuration has the advantages that the cardiac pacemaker is reasonable in atria ventricular conduction recovery detection frequency, and right ventricular pacing can be reduced as far as possible on the basisthat the atria ventricular stability is guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cardiac pacing system. Background technique [0002] The cardiac pacing system (cardiac pacemaker) is an electronic therapy device implanted in the patient's body. It sends out electric pulses powered by the battery through the pulse generator, and stimulates the myocardium contacted by the electrodes through the conduction of the wire electrodes, so that the heart is excited and stimulated. Contraction, so as to achieve the purpose of treating cardiac dysfunction caused by certain arrhythmias. [0003] Physiological pacing is an important development direction in the field of cardiac pacemakers, and reducing right ventricular pacing is one of the important aspects. Many existing pacemakers are committed to developing the function of reducing right ventricular pacing, such as Sorin's SafeR, Dplus; medtronic's MVP; Biotronic's VP Suppression and so on. The basic idea of ​​these ...
