In Silico Investigation into Cellular Mechanisms of Cardiac Alternans in Myocardial Ischemia

Figure 9

Alternate APs and two repolarization currents in consecutive beats after decreasing Iup and increasing . (a) Consecutive APs in the same coordinate system. Repolarization alternans was obvious by comparing duration of action potentials; (b) beat-to-beat alternation in repolarization current ; (c) beat-to-beat alternation in repolarization current .
