Abstract :
It is hoped that nonlinear methods of quantifying beat-to-beat variability in heart rate and blood pressure may complement spectral analysis. Some of the nonlinear mechanisms in the cardiovascular system are summarized, and the difficulties with detecting nonlinear dynamics in measured data such as heart rate are reviewed
