WebA vector of integers corresponding to peaks/valleys. As a peak [valley] is defined as the highest [lowest] value in a series, the function can only define it after a change in direction has occurred. This means that the function will always return the first period after the peak/valley of the data, so as not to accidentally induce a look-ahead ... Webthis is a function i wrote a while back (and it's more general than you need). it finds peaks in sequential data x, where i define a peak as a local maxima with m points either side of it having lower value than it (so bigger m leads to more stringent criteria for peak finding): town hall wokingham

WebDec 21, 2024 · R-peaks are typically the highest peak in an ECG signal. They are part of the QRS-complex which is a characteristic oscillation that corresponds to the contraction of the ventricles and expansion of the atria. Detecting R-peaks is helpful in computing heart rate and heart rate variability (HRV). Example code can be found in the GitHub repo.
