目的：探讨参麦液对离体氧反常心脏的影响。方法：随机将ＳＤ大鼠分成４组，分别予以富氧、乏氧、异搏定和参麦液灌流，记录心肌收缩力与心电曲线，测量冠脉流量与心肌内丙二醛含量。结果：参麦液组灌注能有效恢复受损心肌收缩力（Ｐ＜００１）和丙二醛含量（Ｐ＜００５），不能降低心律失常发生率。结论：应用参麦液作为正性肌力药物时应注意再灌注心律失常的发生
Objective: To investigate the effect of Shenmaiye on isolated oxygen abnormal heart. METHODS: Sprague-Dawley rats were randomly divided into 4 groups and were given oxygen-enriched, hypoxia, Verapamil and Shenmaiye perfusion respectively. The myocardial contractility and ECG curves were recorded. The coronary flow and myocardial MDA content were measured. RESULTS: Infusion of Shenmaiye could effectively restore the contractile force (P<001) and malondialdehyde content (P<005) of the damaged myocardium and could not reduce the incidence of arrhythmia. Conclusion: It is important to pay attention to the occurrence of reperfusion arrhythmia when using Shenmai liquid as a positive inotrope drug.
