ABSTRACT:
A method and apparatus for detecting heartbeats obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. QRS detection logic detects heartbeats in the ECG data. This logic calculates an activity function from a subset of the plurality of ECG waveforms determined to be least noisy, and uses this activity function to search for heartbeats. The QRS detection logic allows for true heartbeats to be detected while discarding false "noise" beats.
