Abstract

The electrocardiogram is probably the most effective screening device in the United States for the recognizing of latent heart disease in middleaged persons.1,2 The increased effectiveness of antihypertensive therapy, as well as a clearer definition of the risk factors in coronary atherosclerosis, suggests that earlier recognition of patients with chronic heart disease would afford a fruitful area for constructive, preventive medicine. The expense of taking and mounting the ECG, as well as the time lag in obtaining expert interpretation, makes the use of routine electrocardiography impractical in many insurance, employment screening, and "check-up" examinations. A device able to select persons with electrocardiographic abnormalities at the time of the original examination would allow these individuals to be identified and scheduled for more extensive cardiovascular evaluation without delay and without compromising physician time with the majority who are not cardiac-disease suspects.
