In the present study, we report evidence that the existence of premature ventricular contractions increases the embedding dimension of the cardiac dynamics. We also analyze patients with congestive heart failure, a severe clinical condition associated with abnormal left ventricular function. Results also show an increase in the embedding dimension of the heart rate variability. We used electrocardiograms collected by ourselves with quality standards that make them comparable with other databases.
