STANDARDS FOR ANALYSIS OF VENTRICULAR LATE POTENTIALS USING HIGH-RESOLUTION OR SIGNAL-AVERAGED ELECTROCARDIOGRAPHY - A STATEMENT BY A TASK-FORCE-COMMITTEE OF THE EUROPEAN-SOCIETY-OF-CARDIOLOGY, THE AMERICAN-HEART-ASSOCIATION, AND THE AMERICAN-COLLEGE-OF-CARDIOLOGY

Sufficient data are available to recommend the use of the high-resolution or signal-averaged electrocardiogram in patients recovering from myocardial infarction without bundle branch block to help determine their risk for developing sustained ventricular tachyarrhythmias. However, no data are available about the extent to which pharmacological or nonpharmacological interventions in patients with late potentials have an impact on the incidence of sudden cardiac death. Therefore, controlled, prospective studies are required before this issue can be resolved. As refinements in techniques evolve, it is anticipated that the clinical value of high-resolution or signal-averaged electrocardiography will continue to increase. © 1991.
