Active implantable medical device for treating heart rhythm disorders, having improved means for detecting atrial arrhythmias

摘要

Heart implant device, such as a pacemaker, defibrillator, etc. has protection means that comprise means for the dynamic adjustment of the means for detection of auricular events such that a detection threshold can be temporarily raised by a first increment for a first duration after detection by the detection means of a ventricular event without detection of a corresponding preceding spontaneous or stimulated auricular event within the same cycle.
