Evolution of Action Potential Alternans in Rabbit Heart during Acute Regional Ischemia

Figure 5

Changes of OAPD (a) and OAPA (b) alternans magnitude and area as a function of time after coronary occlusion. Black and grey columns show the maximum alternans magnitude and area, respectively. comparing alternans magnitude to 3–5 min; and comparing alternans area to 3–5 min and to 6–8 min ischemia time, respectively.
