1. A method for monitoring a heart rate, comprising:

  • receiving a digital heart monitoring signal;

    dividing the digital heart monitoring signal into at least one frame;

    generating a folded correlation value for the center sample in the at least one frame;

    identify the number of peaks folded correlation values based on amplitude and distance parameters of the digital heart monitoring signal in the at least one frame;

    removing false peaks and collecting peaks corresponding to a length of time;

    determining the heart rate based on the identified peaks, wherein the identified peaks relate to a minimum distance between valid heart beat peaks based on a heart rate estimate;

    computing the weighted average of heart rate value based on the number of previous heart rate values; and

    at least one of storing or displaying the computed heart rate value.
