A method and apparatus for cardioverting the atrium of a human heart that includes 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 right 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. Further, after delivery of a successful defibrillation shock, the width of intrinsic p-waves are monitored and bi-atrial pacing is temporarily initiated if the width exceeds a preset or programmable threshold.
An implantable medical device, comprising:
An implantable medical device for delivering a first therapy in response to variations in heart rhythm detected by electrodes inserted within a patient, comprising:
The device of claim 16, wherein the pacer timing/control circuit determines, subsequent to delivery of the second therapy, whether a width of a subsequent p-wave is greater than a predetermined threshold width.
A method for implementing atrial defibrillation, comprising the steps of:
Dependencies are inferred from the claim text.
