ACTIVE MEDICAL DEVICE OF THE IMPLANTABLE DEFIBRILLATOR / CARDIOVERTER TYPE WITH IMPROVED DISCRIMINATION OF EAR FIBRILLATIONS

摘要

This device comprises: means for delivering defibrillation and / or cardioversion therapy and / or ventricular and / or atrial antitachycardia stimulation; means of collecting ventricular and atrial activity; means for suspecting and confirming the presence of episodes of tachycardia in the activity thus collected, these means comprising means for analyzing the stability of the RR intervals and the stability of the associated PR intervals; and discriminating means implemented in the event of detection of stable RR intervals and unstable PR intervals, these means being able to discriminate between atrial fibrillation with rapid ventricular response and ventricular tachycardia, and to order differentiated therapy according to one either case.
