The omnicardiogram Study of a proposed method for detecting coronary heart disease in an asymptomatic population.
A proprietary, commercial technique has been proposed by its inventor as a noninvasive method of detecting subtle electrocardiogram abnormalities, not apparent by conventional means. To study the ability of the omnicardiogram to detect latent coronary heart disease in an asymptomatic population, 200 normal electrocardiograms from the Framingham Study cohort were analyzed by this technique. One-half of these consisted of the last normal electrocardiogram prior to development of clinical coronary heart disease. The omnicardiogram showed a higher degree of sensitivity than did the electrocardiogram to coronary heart disease, indicating an increased risk of myocardial infarction in this group. The low specificity of this technique as indicated by the large percentage of false positives shows that the omnicardiogram is not diagnostic of coronary heart disease in asymptomatic persons with normal electrocardiograms.
