PROCÉDÉS DE DÉTERMINATION D'UNE FENÊTRE VULNÉRABLE À UNE THÉRAPIE DE CHOC À PARTIR D'ÉLECTROGRAMMES EN CHAMP ÉLOIGNÉ DANS DES DÉFIBRILLATEURS AUTOMATIQUES IMPLANTABLES
Methods for determination of timing for electrical shocks to the heart to determine shock strength necessary to defibrillate a fibrillating heart. The timing corresponds the window of most vulnerability in the heart, which occurs during the T-wave of a heartbeat. Using a derivatized T-wave representation, the timing of most vulnerability is determined by a center of the area method, peak amplitude method, width method, or other similar methods. Devices are similarly disclosed embodying the methods of the present disclosure.
