Abstract
A system and method for performing bipolar sensing and pacing in a heart using a unipolar atrial electrode. The invention provides a lead system comprising an atrial electrode placed in the atrium of the heart and a defibrillation electrode placed in the heart. The defibrillation electrode may be placed in the ventricle, the superior vena cava, or the coronary sinus. Bipolar pacing and sensing in the atrium is achieved without the introduction of additional conductors into the atrium.
