Anti-arrhythmic effect of verapamil in an animal model of ischemic arrhythmia.

<p>(A) Protocols for arrhythmia study. (B) Total arrhythmia scores during 45 min of ischemia period. (C)Representative tracings of ECG recordings. Verapamil, a calcium channel antagonist, at 1 mg/kg was i.v. injected into a femoral vein 10 min prior to ischemia. Anti-arrhythmic property of verapamil was evaluated. **<i>P</i><0.01 vs. sham group, ^##<i>P</i><0.01 vs. ischemia group. All values are expressed as mean ± SD, <i>n = </i>10 in each group.
