Implantable medical active device, such as cardiac pacemaker, defibrillator and / or cardioverter AAI or AAI / DDD

摘要

The device has a critical period defining unit which precedes or follows an end of an auricular interval of escape beats (IEA). A detection unit recognizes the appearance of inappropriate functioning conditions and/or false diagnosis of a cardiac rhythm by the device, during the detection of a ventricular extra systole (ESV). A modifying unit modifies the functioning parameters of the device based on the detection result.
