Preprocessing Unevenly Sampled RR Interval Signals to Enhance Estimation of Heart Rate Deceleration and Acceleration Capacities in Discriminating Chronic Heart Failure Patients from Healthy Controls

<div>PRSA curves of synthetic RRI signals at three levels of RRI and average of all RRI signals. (a) PRSA curves of synthetic raw RRI signals. (b) Enlarged view of central oscillations in (a) with window of 15 s for RRI<sub>s-500</sub>. (c) PRSA curves of preprocessed synthetic RRI signals at resampling frequency of 4 Hz. (d) Enlarged view of central oscillations in (c) with window of 15 s for the three curves.</div>
