Title
(EN) METHOD AND MEDICAL DEVICE FOR DISCRIMINATING BETWEEN A SUPRAVENTRICULAR TACHYCARDIA AND A VENTRICULAR TACHYCARDIA
(FR) PROCÉDÉ ET DISPOSITIF MÉDICAL POUR DISTINGUER UNE TACHYCARDIE SUPRAVENTRICULAIRE D'UNE TACHYCARDIE VENTRICULAIRE
Abstract
(EN)
A method (1000-1002) for automatically discriminating between a supraventricular tachycardia event and a ventricular tachycardia event is provided. The method includes sensing a first cardiac signal (100) using a first electrode pair (62, 56) and a second cardiac signal (200) using a second electrode pair (36, 38) during a heartbeat, applying a first algorithm to the first cardiac signal (100) to determine whether the first cardiac signal (100) is indicative for a supraventricular tachycardia or indicative for the ventricular tachycardia; applying a second algorithm to the second cardiac signal (200) to determine whether the second cardiac signal (200) 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 (vt) indicative for the ventricular tachycardia when at least one of the first cardiac signal (100) and the second cardiac signal (200) have been determined to be indicative for the ventricular tachycardia. Furthermore, a medical device and a computer readable storage medium are provided.

L’invention concerne un procédé (1000-1002) permettant de distinguer automatiquement un événement de tachycardie supraventriculaire d'un événement de tachycardie ventriculaire. Le procédé consiste à détecter un premier signal cardiaque (100) à l'aide d'une première paire d'électrodes (62, 56) et un deuxième signal cardiaque (200) à l'aide d'une deuxième paire d'électrodes (36, 38) pendant le battement d'un cœur ; à appliquer un premier algorithme au premier signal cardiaque (100) pour déterminer si le premier signal cardiaque (100) est indicateur d'une tachycardie supraventriculaire ou indicateur d'une tachycardie ventriculaire ; à appliquer un deuxième algorithme au deuxième signal cardiaque (200) pour déterminer si le deuxième signal cardiaque (200) est indicateur d'une tachycardie supraventriculaire ou indicateur d'une tachycardie ventriculaire, le deuxième algorithme de comparaison étant différent du premier algorithme de comparaison ; et à attribuer à un indicateur spécifique du battement du cœur une première valeur (vt) indicatrice de la tachycardie ventriculaire quand au moins l'un du premier signal cardiaque (100) et du deuxième signal cardiaque (200) a été déterminé comme étant indicateur de la tachycardie ventriculaire. En outre, un dispositif médical et un support d'informations lisible par ordinateur sont également décrits.
