[Analysis of the heart rhythm variability using median spectrogram method].
The analysis of the heart rhythm variability (HRV) with the methods of median (built according to some realizations) and traditional spectrogram was carried out in groups of people with different physical conditions and with tilt test. It was shown that median spectrogram characterize the changes of the HRV wave structure more precise than the traditional one with spectrum division into three standard windows.
