INTER-ATRIAL SEPTUM ELECTRODE FOR ATRIAL DEFIBRILLATION

摘要

An implantable system for the defibrillation of the atria of a patient's heart comprises (a) a first catheter (30) configured for insertion into the right atrium of the heart, preferably without extending into the right ventricle of the heart; a first atrial defibrillation electrode (32) carried by the first catheter and positioned at the atrial septum of the heart; (b) a second atrial defibrillation electrode which together with the first atrial defibrillation electrode provides a pair of atrial defibrillation electrodes that are configured for orientation in or about the patient's heart to effect atrial defibrillation, and (c) a pulse generator (42).
