In this paper we address the massive parallelization of the characterization of heartbeats by means of Graphics Processors. Heartbeats are represented with Hermite polynomials due to the compactness and robustness of this representation. Both the off-line and on-line characterization of QRS complexes are covered, thus, assessing the capabilities of Graphics(More)
One of the most promising non-invasive markers of the activity of the autonomic nervous system is Heart Rate Variability (HRV). HRV analysis toolkits often provide spectral analysis techniques using the Fourier transform, which assumes that the heart rate series is stationary. To overcome this issue, the Short Time Fourier Transform is often used (STFT).(More)
