Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
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.
Claim 2
Independent Claim
90 words
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.
Claim 3
Dependent Claim
28 words
A method according to claim 1 wherein said step of delivering a cardioversion pulse further comprises coupling said first and second electrodes to one another during said pulse.
Claim 4
Dependent Claim
45 words
A method according to claim 1 or claim 2 further comprising; locating a fourth electrode adjacent said patient's ventricle; sensing an occurrence of ventricular tachyarrhythmia; and delivering a cardioversion pulse between one or more of said first, second and third electrodes and said fourth electrode.
Claim 5
Dependent Claim
26 words
A method according to claim 3 wherein said step of locating said fourth electrode comprises implanting a pulse generator including a housing having a conductive portion.
