Abstract

The aim of the present contribution is to give a review on a new methodology that we may use when we are employed in the analyis of one of the most fundamental signals that we encounter in electrophysiology, the R-R intervals in analysis of the ECG. First of all the limits of the current FFT application are discussed. Soon after the basic foundations of the CZF method are exposed and we expose and discuss in detail a large number of physiological and clinical applications, based directly on experimental results .The results evidence the importance to use the CZF method as non invasive marker in analysis of HRV. Key words : Heart Rate Variability, CZF method, ANS contribution analysis
