对大鼠股动脉缺血预适应（ＦＩＰ）对缺血再灌注心律失常的延迟性保护作用进行了观察。结果：ＦＩＰ组缺血期室速（ＶＴ）、室颤（ＶＦ）的发生次数和累计持续时间较对照组（ＮＩＰ组）明显减少或缩短（Ｐ＜０．０１），再灌注性心律失常２组间差异不显著，动物死亡率（２０％）较ＮＩＰ组（５０％）降低，但无统计学意义（Ｐ＞０．０５）；ＦＩＰ２４ｈ组再灌注ＶＴ、ＶＦ较ＮＩＰ组明显减少，动物死亡率为０％，与ＮＩＰ组比较有显著性差异（Ｐ＜０．０５）。提示：大鼠ＦＩＰ对心肌缺血再灌注心律失常有明显的保护作用。延迟保护作用较早期保护效应更强，明显减少致命性再灌注ＶＴ、ＶＦ的发生，使动物存活率提高
Delayed protective effect of ischemic preconditioning (FIP) on ischemia-reperfusion arrhythmia in rats was observed. Results: The incidence and duration of ventricular tachycardia (VT) and ventricular fibrillation (VF) in FIP group were significantly decreased or shortened compared with those in control group (P <0.01), reperfusion arrhythmia 2 There was no significant difference between the two groups (P> 0.05). Animal mortality (20%) was lower than that of the NIP group (50%), but there was no significant difference between the two groups The rate was 0%, which was significantly different from NIP group (P <0.05). Tip: FIP rat myocardial ischemia-reperfusion arrhythmia significant protective effect. Delayed protection is more protective effect than the early, significantly reduce the fatal reperfusion VT, VF, the animal survival rate increased
