ABSTRACT:
Control of an anti-tachycardia device such as a defibrillator to apply a preselected programmed therapy in the event of ventricular tachycardia. The control includes comparison of the atrial and ventricular rhythms, and examination of the criteria of stability of the P-R intervals, of the stability of the R-R intervals, and of the acceleration of the ventricular rhythm subsequent to an atrioventricular desynchronization, thereby to ensure control of the antitachycardia device solely in the event of ventricular tachycardia.
