(EN) METHODS, SYSTEMS AND DEVICES FOR DETECTING AND DIAGNOSING HEART DISEASES AND DISORDERS
(FR) PROCÉDÉS, SYSTÈMES ET DISPOSITIFS DE DÉTECTION ET DE DIAGNOSTIC DE CARDIOPATHIES ET DE TROUBLES CARDIAQUES
Abstract
(EN)
Disclosed herein methods, devices, and systems for detecting and diagnosing a heart disease or disorder in a subject from a prime electrocardiogram which comprises calculating at least one distribution function of the prime electrocardiogram and determining whether the distribution function is indicative of the presence of absence of the heart disease or disorder.
(FR)
La présente invention concerne des procédés, dispositifs et systèmes de détection et diagnostic d'une cardiopathie ou d'un trouble cardiaque chez un sujet, à partir d'un principal électrocardiogramme, qui consistent à calculer au moins une fonction de distribution du principal électrocardiogramme et déterminer si la fonction de distribution indique l'absence de cardiopathie ou de trouble cardiaque.
