1. An implantable electrical lead, comprising:

  • an elongated insulative lead body having a proximal end and a distal end;

    a defibrillation electrode comprising a plurality of conductive filaments extending distally from the lead body at a first point between the proximal and distal ends of the lead body and having free distal ends unattached to the lead body;

    a cardiac pacing electrode located at the distal end of the lead body;

    provided with means for fixing the pacing electrode to heart tissue;

    first conductor means coupled to the pacing electrode and extending proximally within the lead body, for coupling the pacing electrode to an implantable cardioverter or defibrillator; and

    second conductor means coupled to the defibrillation electrode and extending proximally within the lead body, for coupling the defibrillation electrode to an implantable cardioverter or defibrillator.
