The Clinical Application of Temporary Pacing in Patients with Acute Inferior Myocardial Infarction

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 of213 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 stricdy applied and the pacing electrode lead should be removal as soon as possible.
