Nearly a million Americans die each year of cardiovascular disease, according to the American Heart Association. The traditional diagnostic methods for cardiac disease--listening with a stethoscope ("auscultation"), examination of graphic records of the audible sounds ("phonocardiography"), or electrocardiogram (ECG) analysis--have been used for years by physicians and other medical personnel to detect abnormalities of the heart. These and related techniques are also used in research to study and compare cardiac activity. While such methods have been invaluable in guiding the physician, a great deal of training is required for proper evaluation, particularly for certain subtle or complicated anomalies.
