Abstract :
Electrocardiograms (ECGs) of two normal subjects were studied using methods of nonlinear dynamics, both in supine rest and standing up. For each signal, the authors computed power spectrum, phase-space portrait, and correlation dimension. They found that the power spectrum shows a 1/f behavior at high frequencies, and that the correlation dimension is 4.7±0.3, suggesting fractal behavior of ECG signals
