This text is the published proceedings of a symposium dedicated to Ernst Simonson, MD, held in Minneapolis, September 28 and 29, 1967. Nearly half of the conference was devoted to the technical problems of engineering in order to obtain noise-free electrocardiographic signals taken during exercise for computer analysis. While it was acknowledged that exercise electrocardiograms can be quantitated by techniques currently available to the clinician, emphasis was placed on advances in data storage and computer analysis which have provided the tools to develop and apply new criteria for the differentiation between a normal and abnormal electrocardiographic response to exercise. The great value of the computer is to reduce electrocardiographic measurement and classification error, relieve humans from tedious tasks, and improve consistency of measurement.

The remainder of the text is devoted to a series of excellent presentations on the physiology of human electrocardiographic response to exercise. Different methods of stress testing
