为研究缺血性应激力（ＩｓｃｈｅｍｉｃＰｒｅｃｏｎｄｉｔｉｏｎｉｎｇＩＰＣ）对猪心再灌注（ＲｅｐｅｒｆｕｓｉｏｎＲｅＰ）性心律失常的影响，二组载体猪心（对照组ｎ＝９，治疗组ｎ＝１０）的左冠状动脉前降支完全阻断１０分钟／ＲｅＰ５分钟，重复３次。对照组：室颤（ＶＦ）发生率为８９％、６７％、３０％，Ｐ＜０．０１，发生时间（秒）１４．５±１．４，１１９．８±１３．８，４８±１２．５，Ｐ＜０．０１。治疗组：ＶＦ发生率为４０％，３０％，３０％，发生时间（秒）１５．２±６．４，１２６．５±１８．６，９７±２３．４，Ｐ＜０．０１。心肌缺血性应激力对猪心ＲｅＰ性心律失常具有保护作用。
To investigate the effect of Ischemic Preconditioning IPC on pig reperfusion (Arrhythmia), the left anterior descending coronary artery of the two groups of pig heart (n = 9 in the control group and n = 10 in the treatment group) Completely blocked for 10 minutes / ReP5 minutes, repeated 3 times. Control group: The incidence of ventricular fibrillation (VF) was 89%, 67%, 30%, P <0.01, time of occurrence (seconds) 14.5 ± 1.4, 119.8 ± 13.8, 48 ± 12 .5, P <0.01. In the treatment group, the incidence of VF was 40%, 30%, 30%, and the time of onset (seconds) was 15.2 ± 6.4,126.5 ± 18.6,97 ± 23.4, P <0.01. Myocardial ischemic stress has a protective effect on pig heart ReP arrhythmia.
