Title
(EN) METHOD AND APPARATUS FOR IMPROVING THE ACCURACY OF INTERPRETATION OF ECG-SIGNALS
(FR) PROCEDE ET APPAREIL POUR AMELIORER LA PRECISION DE L'INTERPRETATION DES SIGNAUX D'ECG
Abstract
(EN)
An electrocardiographic measurement system, method and device uses a device such as an inclinometer, which measures the body position in three orthogonal planes x, y and z in order to correct the calculated vector for changes in ECG parameters, especially S-T segment level during ischemic attacks. Recordings are made with a sixteen channel recorder for twenty four hours and so it is necessary to have a measure of the posture of the subject to interpret the ECG. An inclinometer, which measures gravitational acceleration in all planes to the nearest degree is used, giving three traces for the three planes x, y and z. by initial calibration of the ECG changes due to body position or continuous running average the calculated vector of the ECG can be corrected by standard geometric methods.

Selon cette invention, un système électrocardiographiques et un procédé et un dispositif de mesure correspondants utilisent un dispositif tel qu'un clinomètre qui mesure la position d'un corps dans trois plans orthogonaux x, y et z afin de corriger le vecteur calculé en fonction des changements dans les paramètres d'ECG, notamment au niveau du segment S-T lors des accidents ischémiques. Les enregistrements s'effectuent pendant vingt-quatre heures avec un enregistreur à seize voies, c'est pourquoi il est nécessaire de mesurer la position du sujet pour interpréter correctement l'ECG. On utilise un clinomètre, qui mesure la décélération gravitationnelle dans tous les plans jusqu'au degré le plus proche en laissant des traces pour les trois plans x, y et z. L'étalonnage initial des changements survenus dans l'ECG en raison de la position du corps ou de la moyenne courante continue permet de corriger le vecteur calculé de l'ECG par des procédés géométriques standard.
