1. An epicardial electrode, comprising:
- a flexible member of insulative material;
a plurality of elongated, flexible insulative sheets, each having a first end mounted to said member and a second, free end extending from said member, said member and said flexible insulative sheets capable of assuming a generally planar configuration;
a plurality of electrodes, at least one electrode mounted to each of said plurality of flexible elongated insulative sheets;
an elongated insulated electrical conductor having a distal end coupled to each of said plurality of electrodes; and
an electrical connector coupled to the proximal end of said elongated insulative conductor.

Abstract
A cardioversion and defibrillation lead system and a method of use of the lead system for applying energy to the heart. The lead system and method of application are designed to maximize the efficiency of electrical energy and depolarizing the cells of the heart by equalizing current distribution across the heart and concentrating current in the muscular areas of the heart. The method of use of the lead system includes properly locating the electrodes, and applying pulses to the electrodes in one of several pulse regimes.
