1. Apparatus for monitoring a succession of heartbeats and estimating heart rate, comprising:

  • first and second electrodes adapted to contact a patient and transmit an EKG signal indicative of heartbeat activity;

    heart rate means, connected to the first and second electrodes, for monitoring the EKG signal and estimating heart rate;

    means for coupling a prescribed continuity signal to the first electrode, for transmission through the patient to the second electrode;

    means for detecting the presence of the continuity signal at the second electrode and producing an inhibit signal whenever the continuity signal is not detected; and

    means for inhibiting the heart rate means in response to the inhibit signal.
