目的：探讨临时起搏在急性下壁心肌梗死接受急诊冠状动脉介入治疗术（PCI）患者中应用的适应证及时机.方法：回顾性分析我院2003年1月至2013年1月成功行急诊PCI的下壁心肌梗死213例的临床资料,其中行临时起搏治疗84例,未行临时起搏治疗129例.结果：临时起搏并不减少急性下壁心肌梗死的住院心血管事件发生率,且长时间使用（＞48 h）或保护性临时起搏在急性下壁心肌梗死患者中增加室性心律失常、感染、心脏破裂的机会,且延长住院日.结论：临时起搏在急性下壁心肌梗死中的应用应严格把握指征并尽快拔除.

英文摘要：

Objective：To explore the indications and timing of temporary pacing applications in patients with acute inferior myocardial infarction underwent emergency coronary intervention （PCI）. Methods： The clinical data of 213 patients with inferior myocardial infarction successfully underwent emergency PCI were analyzed retrospectively from Jan 2003 to Jan 2013, the 84 cases were taken temporary pacing therapy （pacing group）, while 129 cases not （control group）. Results： The hospitalization incidence of cardiovascular events was not reduced by temporary pacing in acute inferior wall myocardial infarction, and the prolonged use （more than 48 h） or protective temporary pacing in the cases increased the incidence of ventricular arrhythmias, infections, cardiac rupture and extended the length of hospitalization. Conclusion： The indications of temporary pacing in patients with acute inferior myocardial infarction should be strictly applied and the pacing electrode lead should be removal as soon as possible.
