Electrode arrangement for an implantable defibrillator/cardioverter
 An electrode arrangement for an implantable defibrillator/cardioverter has two intravascular electrodes, one of which is disposed in the inferior vena cava. The arrangement has a third, planar electrode, which is disposed outside of the heart. Placement of one of the intravascular electrodes in the inferior vena cava, instead of in the right ventricle as in known systems, achieves a high utilization of the defibrillation energy without the presence of an endocardial electrode.
