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>Squared central wavelet coefficients of PRSA curves obtained after interpolation and resampling at different scales. The shaded area represents the variation range of each curve. (a) Wavelet analysis using the third-order Gaussian wavelet. The maximum coefficients occur at scale <i>s</i> = 6.2. (b) Wavelet analysis using the Haar wavelet. The maximum coefficients occur at scale <i>s</i> = 14.0.</div>
