心肌再灌注所致缓慢性心律失常的临床分析

Clinical analysis of slow arrhythmia caused by myocardial ischemia reperfusion

目的:探讨心肌再灌注所致缓慢性心律失常的临床特点。方法:收治急性心肌梗死行急诊PCI治疗过程中心肌再灌注所致缓慢性心律失常患者98例,回顾性分析其临床资料。结果:心肌再灌注所致缓慢性心律失常发生在血管开通时间≤6 h者(62例)明显高于血管开通时间6~12 h者(36例)(P<0.05)。右冠近中段心肌再灌注致缓慢性心律失常的发生明显高于其他部位(P<0.05)。结论:右冠近中段闭塞患者早期行急诊PCI治疗时更易发生缓慢性心律失常,应做好相关预防及抢救准备,以防止不良事件发生。

Objective:To explore the clinical characteristic of slow arrhythmia caused by myocardial ischemia reperfusion.Methods:98 patients with slow arrhythmia caused by myocardial ischemia reperfusion during emergency PCI treatment because of acute myocardial infarction were selected.The clinical data were retrospectively analyzed.Results:The patients(62 cases) with slow arrhythmia caused by myocardial ischemia reperfusion at the occurrence time of less than 6 hours after the opening of blood vessels were more than patients(36 cases) at the occurrence time of 6 to 12 hours after the opening of blood vessels(P<0.05).Slow arrhythmia caused by myocardial ischemia reperfusion at the proximal and middle of right coronary artery was significantly higher than other parts(P<0.05).Conclusion:Patients with occlusion at the proximal and middle of right coronary artery with early emergency PCI treatment were more likely to slow arrhythmia.We should prepare related prevention and treatment,so as to prevent adverse events.
