ABSTRACT:
A method and apparatus for calculating a heart rate obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. Heart rate calculation logic calculates the patient's heart rate. This logic determines the intervals between the heartbeats detected in the ECG data, discards a percentage of the shortest and longest intervals, and averages the remaining intervals to arrive at the patient's heart rate. This results in a robust calculation of the heart rate even in the presence of noise falsely detected as heartbeats and missed beats, both of which are common in noisy environments. The heart rate is displayed to the cardiologist or medical professional for diagnosis of the condition of the patient's heart.
