Implantable arrangement for the defibrillation or cardioversion of a heart
 An implantable arrangement for effecting in vivo defibrillation or cardioversion of a heart has a first electrode disposed in the inferior vena cava, a second electrode disposed in the right ventricle, and a planar electrode disposed outside of the heart. Pulse generating means are provided which simultaneously charge all three electrodes with pulses. An optimally low energy for successfully achieving defibrillation is thereby achieved.
