A-B. Method of quantitation of action potential (AP) and J wave parameters. C. Measurement of dispersion of AP repolarization. D. Measurement of dispersion of repolarization when the AP dome is lost at one epicardial (Epi) site but not the other. APD90 = action potential duration at 90% repolarization; EDR = epicardial dispersion of repolarization; Endo = endocardial; TDR = transmural dispersion of repolarization.
