1. An apparatus comprising:

  • sensing circuitry configured for sensing electrical activity of a muscle segment of a heart;

    one or more implantable electrodes, wherein said electrodes are adapted to convey an electrical signal to the muscle segment of the heart; and

    pacing circuitry for pacing the heart, wherein said pacing circuitry is adapted to drive the electrodes to apply the signal to the segment by driving an electrical current into the segment, the current having an amplitude of at least 3 mA and less than 20 mA, and a signal duration, in a cardiac cycle, of between 10 and 140 msec, wherein the signal is applied in response to the sensing with a delay relative to the preceding sensed electrical activity.
