２２例急性心肌梗死患者接受经皮冠状动脉内血栓溶解治疗，经即刻冠状动脉造影证实１４例冠状动脉再通。９例（６４．３％）发生再灌注性心律失常（ＲＡ）。１４例中７例（５０．０％）为室性ＲＡ，３例（２１．４％）发生加速性室性自主节律，后者为提示再灌注的特异性较高的指标。一过性缓慢性心律失常的５例（３５．８％）均发生在下壁及（或）后壁梗死。ＲＡ的发生与再灌注前心肌缺血时间和缺血性心律失常存在与否无关，心肌功能严重受损患者可能更易发生ＲＡ。本文并就如何预防和治疗ＲＡ进行了探讨。
Twenty-two patients with acute myocardial infarction underwent percutaneous coronary thrombolysis and 14 patients with recanalization of the coronary artery were confirmed by immediate coronary angiography. Nine patients (64.3%) had reperfusion arrhythmias (RA). Among the 14 cases, 7 cases (50.0%) had ventricular RA and 3 cases (21.4%) had accelerated ventricular autonomic rhythm. The latter was a specific indicator of reperfusion. Five cases (35.8%) of transient bradyarrhythmias occurred in the inferior and / or posterior wall infarcts. The occurrence of RA is not related to the time of myocardial ischemia before reperfusion and the existence of ischemic arrhythmia. RA may be more likely to occur in patients with severe myocardial dysfunction. This article also discusses how to prevent and treat RA.
