Figure 2

Cellular basis for normal T‐wave inscription. Shown here is the temporal relationship between transmembrane action potentials recorded from epicardial, M region, and endocardial (A) or subendocardial Purkinje fiber regions (B). Note that M cell repolarization is aligned with end of the T wave, whereas repolarization of the epicardial cells is coincident with the peak of the T wave. ECG indicates electrocardiogram; Endo, endocardial; Epi, epicardial; M Cell, Masonic myocardial Moe cell.
