Abstract
Application of dynamic and quantitative methods to exercise electrocardiography has lagged partly because of technical difficulties in acquiring exercise electrocardiographic signals and partly because of limitation imposed by the conventional means of ECH registration. Contemporary methods relieve these restrictions and permit changes in response to exercise stress to be measured as they occur, so that the time-course of response becomes a significant variable. This permits the adoption of an exercise stress method which becomes part of a closed feedback loop with individual response to exercise determining the cut off point of the stress. Such a stress test is shown to be reproducible to a satisfactory degree and effective in detecting ischemic heart disease.
A visual method for quantitating exercise ST segment response is illustrated. Its use will reduce interobserver variation in the evaluation of exercise ECGS. A computer method of processing exercise ECGS is described. It eliminates human variability in measurement as well as reducing physician time and effort requirements in evaluating exercise ECG response.
