Abstract
A method and apparatus for treating atrial tachyarrhythmias, particularly atrial fibrillation. High energy pulses are delivered between electrodes located in the right atrium/SVC, the left pectoral region and the coronary sinus/great vein, with the left pectoral and coronary sinus/great vein electrodes connected in common. Optionally a ventricular electrode may also be employed in conjunction with one or more of the other listed electrodes to accomplish ventricular cardioversion or defibrillation.
Claims4
A method of cardioverting a patient's heart, comprising:
- locating a first electrode in the coronary sinus of said patient's heart;
- locating a second electrode subcutaneously in a left pectoral location in said patient's chest;
- locating a third electrode in the right atrium/superior vena cava portion of said patient's heart;
- sensing an occurrence of atrial tachyarrhythmia;
- coupling said first electrode to said second electrode;
- and
- delivering a cardioversion pulse between said first and third electrodes and between said second and third electrodes in response to a detected occurrence of atrial tachyarrhythmia.
