Frequency domain analysis of Heart Rate Variability in ecgAUTO

This is the first document of our serie of technical notes discussing Heart Rate Variability (HRV) analysis.

It introduces the Frequency Domain analysis, which is an effective method to analyze heart rate dynamics. In this document, you will learn how ecgAUTO software uses your data to produce HRV values, using the Fast Fourier Transform (FFT).
