1. A wearable physiological measurement system comprising:

  • a wearable strap configured to be couplable to an appendage of a user, the wearable strap comprising;

    one or more light emitters for emitting light toward the user'"'"'s skin,one or more light detectors for receiving light reflected from the user'"'"'s skin, andan electronic circuit board comprising a processing module configured for analyzing data corresponding to the reflected light to automatically and continually determine a sequence of instantaneous heart rate of the user;

    wherein the processing module is configured to determine a heart rate of the user by;

    executing one or more computer-executable instructions associated with a peak detection algorithm to process the data corresponding to the reflected light to detect a plurality of peaks associated with a plurality of beats of the user'"'"'s heart,determining an R-wave-to-R-wave interval (RR interval) based on the plurality of peaks detected by the peak detection algorithm,determining a confidence level associated with the RR interval, andbased on the confidence level associated with the RR interval, selecting either the peak detection algorithm or a frequency analysis algorithm to process data corresponding to the reflected light to determine the sequence of instantaneous heart rates of the user.
