An endocardial lead comprising an elongate body having a first defibrillation coil electrode, a second defibrillation coil electrode and a first pacing/sensing electrode. The first defibrillation coil electrode has a first end and a second end, where the first end is at or near the distal end of the elongate body and the second end spaced longitudinally from the distal end. The first pacing/sensing electrode is spaced longitudinally along the peripheral surface from the second end of the first defibrillation coil electrode. The second defibrillation coil electrode is spaced longitudinally along the peripheral surface from the first pacing/sensing electrode to afford positioning the first defibrillation coil longitudinally adjacent an apical location of the right ventricle of a heart with the first pacing/sensing electrode within the right ventricle of the heart and the second defibrillation coil within the right atrial chamber or a major vein leading to the right atrial chamber of the heart. The elongate body further includes a curved portion on which the first pacing/sensing electrode is positioned such that the first pacing/sensing electrode extends beyond the peripheral surface of the elongate body to engage the tissue of the heart. The first pacing/sensing electrode further includes a retaining element, where the retaining element is adapted to be embedded in the right ventricle of the heart to secure the first pacing/sensing electrode and the elongate body of the endocardial lead to the right ventricle of the heart.
