Method for computing the heartrate variability for use in an ECG-monitor and an ECG-monitor comprising such a computational program

摘要

a method to calculate the herzratenvariabilitu00e4t of the human heart for use in an ecg monitor has the following steps:- scanning of ecg monitor ecg signal received during a abtastintervalls,- identification of a number of discrete, for the herzratenvariabilitu00e4t representative values from the sampled ecg signals- evaluation of these measurements on the basis of fourier transform, and the spectrum of measured values from the fourier coefficients of the fourier transformation is calculated, which in turn from a linearkombination the measurements with the sinus and kosinusfu00f6rmigen fourier vectors. urier transformation are calculated.with the fourier vectors, each in the form of a series of discrete real vector values are included in the calculation.replace the vector values for the calculation of the frequency spectrum of the sampled measured values by big integer vector approximations, a limited number, the course of the fourier vectors roughly reproduce.
