Embodiment Construction

[0024] 1 is a conceptual diagram of an example multi-chamber leadless pacing system 101 that can be used to sense cardiac electrical signals and myocardial torsion forces caused by myocardial torsion, and provide pacing therapy to a patient's heart 100 . The multi-chamber leadless pacing system 101, in some examples, may include a right ventricular (RV) intracardiac pacemaker 200, a right atrial (RA) intracardiac pacemaker 300, or a combination of other different chamber pacemakers. Pacemakers are transcatheter intracardiac pacemakers that may be adapted for implantation entirely within a chamber of the heart 100, e.g., entirely within the RV, entirely within the left ventricle (LV), entirely within the RA Or entirely within the left atrium (LA). In the example of FIG. 1 , pacemaker 300 is positioned along the endocardium of the RA (eg, along the lateral wall of the RA or the septum of the RA). Pacemaker 200 is positioned along the endocardial wall of the RV (eg, the RV apex)...

Abstract

The invention discloses a perception pace-making method of a multi-chamber non-conductor pacemaker system. A multi-chamber non-conductor pacemaker system comprises one or a plurality of pacemakers implanted into a human body, the pacemakers comprise mechanical sensing modules, electrocardiogram perception modules, processing modules, communication modules, pace-making modules, power supply modules, storages and the like. The pacemakers judge cardiac activity conditions and electrocardiogram conditions according to cardiac mechanical events and cardiac electrical events received by the processing modules, so that accurate pace-making is achieved, and cardiac activities are adjusted and controlled. Mechanical sensors perceive the cardiac mechanical events by sensing related myocardial cell torsion of myocardial cell contraction and relaxation and the like. Different pacemakers of the multi-chamber non-conductor pacemaker system are connected trough the perceived cardiac mechanical eventsand / or the cardiac electrical events, so that cooperative working is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a sensing pacing method for a multi-chamber leadless pacemaker system. Background technique [0002] Cardiac pacemaker is an electronic therapy device implanted in the body. It sends out electric pulses powered by batteries through a pulse generator, and through the conduction of wire electrodes, it stimulates the myocardium in contact with the electrodes, making the heart excited and contracted, so as to achieve therapeutic effect. For the purpose of cardiac dysfunction due to certain arrhythmias. In addition to the above-mentioned pacing functions, the pacing system also has the sensing function of transmitting the heart's own electrical activity back to the pulse generator. [0003] In some examples, a leadless pacemaker implantable in a patient's ventricle includes one or more electrodes on its housing to deliver pacing pulses and / or sense electrical activity of th...
