An algorithm that uses adaptive thresholds for rejecting those beats different from the given threshold more than a certain value. The rule for beat acceptation or rejection is to compare with previous, following and with the updated mean. We apply also a comparison with acceptable physiological values (default values 25 and 200 bpm).
Data structure that stores the beats register and information related to it
long
Number of beats to calculate the updated mean
last
Initial threshold
minbpm
Minimum physiologically acceptable value for HR
maxbpm
Maximum physiologically acceptable value for HR
mini
Deprecated argument maintained for compatibility
maxi
Deprecated argument maintained for compatibility
fixed
Deprecated argument maintained for compatibility
verbose
Deprecated argument maintained for compatibility, use SetVerbose() instead
Value
Returns HRVData, the structure that contains beat positions register, associated heart rate instantaneous values also, and now filtered heart rate signal
