Heart rate variability: for real doctors. Translation from the Russian version of the book, published at Kharkiv, 2010, 131 p.
The basics and practice of the clinical use of the technology of heart rate variability are outlined for doctors of all specialties and students of medical faculties of universities.

Autocorrelation analysis of HRV

The autocorrelation function of the RR-interval series calculates, which is a graph of the correlation coefficients obtained by its successive shift by one RR-interval for its own set. Since the autocorrelation function and the spectrum of the process are connected by a pair of Fourier transforms, the use of autocorrelation or spectral analysis is a matter of the researcher’s taste. The indicators used for practical purposes present in Table. 2.3.
