Abstract :
Proposed is a method to analyze the heart rate variability (HRV) through PP interval. The PP interval is determined using a QRS detector and a new time delay estimate that improves the accuracy of the QRS detection. Results obtained by this method are presented. The extension of the method to measure RR and TT intervals and the effect of sampling rate are considered. Also a discussion about the PP and RR intervals is presented by means of the PR variability analysis
