1. An implantable cardiac stimulation system capable of sensing electrical activity of the heart in all four chambers of the heart and delivering pacing and defibrillation pulses to all four chambers of the heart, the system comprising:

  • a lead system consisting of first and second leads, the first lead including a right atrial pacing electrode for placement in the right atrium, a right ventricular pacing electrode for placement in the right ventricle, a right ventricular defibrillation electrode for placement in the right ventricle, and a right atrial defibrillation electrode for placement in the right atrium and/or the superior vena cava of the heart, the second lead including a right atrial bipolar pacing electrode for placement in electrical contact with the right atrium, a left ventricular pacing electrode for placement in electrical contact with the left ventricle, a left ventricular defibrillation electrode for placement in electrical contact with the left ventricle, a left atrial pacing electrode for placement in electrical contact with the left atrium, and a left atrial defibrillation electrode for placement in electrical contact with the left atrium of the heart;

    wherein the right atrial bipolar pacing electrode is positioned on the second lead between the right atrial pacing electrode of the first lead and the left atrial defibrillation electrode of the second lead, the right atrial bipolar pacing electrode having a first electrode and a second electrode, and the right atrial pacing electrode having a third electrode and a fourth electrode; and

    a cardiac stimulation device including a pulse generator that delivers defibrillation pulses between any combination of the defibrillation electrodes and pacing pulses to any one of the pacing electrodes and a sensing circuit that senses electrical activity of the heart with any one of the pacing electrodes.
