IEEE Transactions on biomedical engineering, 1986•ieeexplore.ieee.orgWe present a simple efficient algorithm for the derivation of a heart rate signal from the
electrocardiogram. We demonstrate that the amplitude spectrum of this heart rate signal
more closely matches that of the input signal to an integral pulse frequency modulation
(IPFM) model of the heart's pacemaker than do the spectra of other ECG-derived heart rate
signals. The applicability of this algorithm in cross-spectral analysis between heart rate and
other physiologic signals is also discussed.
