Title
(EN) METHOD AND MEDICAL DEVICE FOR DISCRIMINATING BETWEEN A SUPRAVENTRICULAR TACHYCARDIA AND A VENTRICULAR TACHYCARDIA
Abstract
(EN)

A method for automatically discriminating between a supraventricular tachycardia event and a ventricular tachycardia event is provided. The method includes sensing a first cardiac signal using a first electrode pair and a second cardiac signal using a second electrode pair during a heartbeat, applying a first algorithm to the first cardiac signal to determine whether the first cardiac signal is indicative for a supraventricular tachycardia or indicative for the ventricular tachycardia; applying a second algorithm to the second cardiac signal to determine whether the second cardiac signal is indicative for the supraventricular tachycardia or indicative for the ventricular tachycardia, the second comparison algorithm being different from the first comparison algorithm; and assigning to a heartbeat-specific indicator a first value indicative for the ventricular tachycardia when at least one of the first cardiac signal and the second cardiac signal have been determined to be indicative tor the ventricular tachycardia.
