N2 - A study was performed to analyze the signal obtained from a noninvasive
photo-plethysmographic device from four subjects in different clinical
conditions. With the help of the theory of nonlinear dynamics, it is
verified that the cardiovascular dynamics is dominated by an underlying
chaotic attractor. A new robust and computationally efficient method is
presented for the detection of the hidden deterministic structure of a
time series. It is shown that the degree of chaos as well as the
underlying determinism is directly related to the subject's clinical
stability.
