Key result
Acidic reperfusion for at least 2 minutes significantly reduced the overall incidence of ventricular fibrillation in isolated rat hearts compared to control (42% vs 92%, P<0.05).
Why the study?
Does acidic reperfusion reduce ventricular fibrillation and improve Na(+)-K(+)-ATPase activity in regionally ischemic rat hearts?
Does acidic reperfusion reduce ventricular fibrillation and improve Na(+)-K(+)-ATPase activity in regionally ischemic rat hearts?
Absolute Event Rate: 42% vs 92%
p-value: p=<0.05
Acidic reperfusion for at least 2 minutes provides sustained protection against ventricular fibrillation in ischemic rat hearts, potentially by enhancing Na(+)-K(+)-ATPase activity recovery.

Acidic reperfusion may reduce VF in rat ischemia models; hypothesis-generating and requires validation before clinical consideration.
Avkiran et al. (1996) studied Ischemia/reperfusion injury and arrhythmias (n=100). Acidic reperfusion (pH 6.6) vs. pH 7.4 buffer (control) was evaluated on Overall incidence of ventricular fibrillation (VF) (p=<0.05). Acidic reperfusion for at least 2 minutes significantly reduced the overall incidence of ventricular fibrillation in isolated rat hearts compared to control (42% vs 92%, P<0.05).
