Abstract
A medical device is disclosed for implantation on an epicardial surface of the heart. The device has a transmural member providing optimal electrode locations for various therapies. The hemodynamically optimal therapy is guided by sensed left ventricular pressure and electrical activity. The device may be used alone or with a companion implanted cardiac rhythm management device.
