Abstract
An implantable cardiac stimulation system and lead is capable of sensing electrical activity of the right and left heart and delivering stimulation pulses to the right and left heart. The system includes a single cardiac lead including a left ventricular pacing electrode, a left ventricular defibrillation electrode, a left atrial pacing electrode, a left atrial defibrillation electrode, and a right atrial pacing electrode. The system further includes a cardiac stimulation device including a pulse generator for delivering pacing pulses to any combination of the pacing electrodes, delivering defibrillation pulses to any combination of the defibrillation electrodes, and sensing electrical activity with any combination of the pacing electrodes. The lead is implantable in the coronary sinus of the heart and may further include a right atrial defibrillation coil electrode.
