In the present study, the authors report evidence that the existence of premature ventricular contractions increases the embedding dimension of the cardiac dynamics. They 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. They used electrocardiograms collected by themselves with quality standards that make them comparable with other databases.
