Wavelets and Multifractal Analysis
Abstract
The human heart generates the quintessential biological signal: the heartbeat. A recording of the cardiac-induced skin potentials at the body's surface, an electrocardiogram (ECG), reveals information about atrial and ventricular electrical activity. Abnormalities in the temporal durations of the segments between deflections, or of the intervals between waves in the ECG, as well as their relative heights, serve to expose and distinguish cardiac dysfunction. Because the electrical activity of the human heart is influenced by many physiological mechanisms, electrocardiography has become an invaluable tool for the diagnosis of a variety of pathologies that affect the cardiovascular system 1. Electrocardiologists have come to excel at visually interpreting the detailed form of the ECG wave pattern and have become adept at differential diagnoses.
