1. Apparatus for monitoring an EKG signal and estimating heartbeat 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 heartbeat rate;

    artifact detection means for monitoring the EKG signal to detect the occurrence of heartbeat artifacts therein and for producing a corresponding inhibit signal; and

    means for inhibiting the heart rate means in response to the inhibit signal, whereby the estimate of heartbeat rate is substantially unaffected by the occurrence of heartbeat artifacts.
