1. A method for generating a heart rate variability measurement for a system for playing back recorded ECG data, the method comprising the steps of:

  • playing back the recorded ECG data to generate a plurality of corresponding output ECG signals;

    defining a reference point on each output ECG signal;

    measuring a period between the reference points on a first output ECG signal and a second adjacent output ECG signal;

    adjusting the period by an amount necessary to align the reference points of the first and second output ECG signals;

    determining the heart rate variability measurement responsive to the adjusted period; and

    displaying the heart rate variability measurement.
