Apparatus for treating atrial tachyarrhythmias with synchronized shocks

摘要: An implantable anti-tachyarrhythmia device which delivers atrial cardioversion or defibrillation pulses heart in response to detection of tachyarrhythmias. The are synchronized and ventricular events such a fashion as assure they occur outside the vulnerable periods associated with both chambers. is provided pulse synchronizer defines first synchronization interval initiated following sensed event second responsive triggerer triggers delivery intervals simultaneously being underway. In particular, may be initiation during interval. addition, also define minimum time additionally expiration defined preceding currently
