1. An implantable cardiac stimulating device for administering pacing pulses to cardiac tissue through an implantable stimulation lead, the device comprising:

  • a pacing pulse generator for generating the pacing pulses;

    input circuitry for receiving a signal representative of cardiac wall motion; and

    control circuitry, coupled to the pacing pulse generator and the input circuitry, for regulating the pacing pulse generator and for evaluating the signal representative of cardiac wall motion to determine when the pacing pulses evoke cardiac contractions.
