Abstract	The characterization of heart dynamics to distinguish abnormal from normal behavior is an exciting topic in clinical sciences. Here we present an analysis of the Electrocardiogram (ECG) signals from several healthy and unhealthy subjects using the framework of the dynamical systems approach and multifractal analysis. The results thus obtained reveal that the attractor underlying the dynamics of the heart has multifractal structure and the variations in the resultant multifractal spectra can clearly separate healthy subjects from unhealthy ones. We use supervised machine learning approach to build a model that predicts the group label of a new subject with very high accuracy from the multifractal parameters. The talk is expected to be of interest to physicists, mathematicians and biologists alike.
