Abstract
A method of cardioverting the atrium of a human heart, comprising insertion of first and second elongated electrodes tranvenously into the heart and associated vessels. One electrode is preferably located in the coronary sinus and great vein of the heart. The other electrode is preferably located in the vicinity of the atrium of the heart, spaced from the electrode located in the coronary sinus. In response to detection of fibrillation or in response to manual triggering, a defibrillation pulse is applied between the first and second electrodes to effect atrial cardioversion.
Claims7
A method of cardioverting or defibrillating a heart, comprising;
- transvenously inserting a first elongated electrode into the great vein and coronary sinus of said heart;
- transvenously inserting a second elongated electrode into the atrium or superior vena cava of said heart, spaced from said first electrode;
- and
- delivering a cardioversion or defibrillation pulse between said first and second electrodes.
A method according to claim 1 or claim 2 or claim 4 wherein said step of inserting said first electrode comprises inserting said first electrode entirely within the coronary sinus and great vein of said heart and spaced from the opening of the coronary sinus into the atrium of said heart.
A method of cardioverting or defibrillating a heart, comprising;
- transvenously inserting a first elongated electrode into the great vein and coronary sinus of said heart;
- transvenously inserting a second elongated electrode into the atrium or superior vena cava of said heart, spaced from said first electrode;
- and
- delivering a cardioversion or defibrillation pulse between said first and second electrodes wherein said steps of inserting said first electrode and inserting said second electrode comprise inserting a single lead carrying said first and second electrodes such that said lead passes through the atrium of said heart and terminates in the great vein of said heart.
