1. An apparatus comprising:

  • an implantable electrostimulation device;

    the implantable electrostimulation device selected from the group consisting of a cardiac pacemaker, cardioverter-defibrillator, and a cardiac resynchronization therapy device;

    a plurality of sensing and pacing elements; and

    a fiber optic lead extending in a sealed relationship from the electrostimulation device to the plurality of sensing and pacing elements, the fiber optic lead having multiple discrete conductors and a drawn fiber core comprising silica or glass, a polymer cladding on the fiber core, and a coaxial conductive metal layer over the polymer cladding, wherein the fiber optic lead is configured and arranged to simultaneously deliver an electrical signal to or from a first sensing and pacing element and an optical signal to or from a second sensing and pacing element.
