FilterNIHR {RHRV} | R Documentation |
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 (25 and 200 bpm).
FilterNIHR(HRVData, long = 50, mini = 12, maxi = 20, fixed = 10, last = 13, verbose = FALSE)
HRVData |
Data structure that stores the beats register and information related to it |
long |
Number of beats to calculate the updated mean |
mini |
Minimum threshold |
maxi |
Maximum threshold |
fixed |
Fixed part of the threshold |
last |
Initial threshold |
verbose |
Boolean argument that allows to specify if the function returns additional information |
Returns HRVData, the structure that contains beat positions register, associated heart rate instantaneous values also, and now filtered heart rate signal
