Pulse stimulation equipment capable of effectively avoiding pacing in atrial vulnerable period

Abstract

The invention discloses pulse stimulation equipment capable of effectively avoiding pacing in an atrial vulnerable period. The pulse stimulation equipment comprises an atrial sensing module, a pacing control module, an atrial pacing module, a clock / timing module and a storage module, the atrium sensing module senses and sends an atrium activity signal to the pace-making control module; when the pace-making control module recognizes an atrial activity signal as an atrial perception event in a non-stress period, the clock / timing module is controlled to time a T1 period and a T2 period which are stored in the storage module and adjacent in time sequence according to the T1 period and the T2 period which are stored in the storage module and adjacent in time sequence; the pacing control module inhibits the atrial pacing module from issuing an atrial pacing event when it is determined that the expected atrial pacing event occurs at the T2 period. The problem of atrial fibrillation danger caused by pacing in the atrial vulnerable period is solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pulse stimulation device capable of effectively avoiding pacing in the vulnerable period of the atrium. Background technique [0002] Implantable medical equipment is an electronic therapeutic device implanted in the body. The pulse generator sends out electric pulses powered by the battery, and through the conduction of the wire electrodes, it stimulates the myocardium in contact with the electrodes to excite and contract the heart, thereby achieving The purpose of treating cardiac dysfunction due to certain arrhythmias. [0003] After cardiomyocytes generate action potentials, they will completely or partially lose their excitability within a short period of time. At this time, if cardiomyocytes are stimulated again, no new action potentials will be generated. This feature is called cardiac refractory period. Cardiac refractory period is divided into abso...
