对采用溶栓治疗的37例急性心肌梗死患者同时进行Holter监测，以研究再灌注心律失常（RA）的过程和特点。再灌注组与未灌注组比较：两组心律失常总发生率均为100％；但加速性室性自主心律（AIVR）只发生于前者，其发生率为76．2％；前者窦性心动过缓的发生率为42．9％，显著比后者的12．5％要高，差异具有显著性（P＜0．05）；前者的室性心律失常在再灌注后的最初8h内发生较频繁，而后者无此现象。作者认为，RA的发生与心肌缺血时间无关，AIVR及一过性窦缓分别为预示再灌注和下壁梗死再灌注的可靠指标。大多数室性RA呈良性经过，不必常规应用抗心律失常药物，但个别患者仍应给予治疗。
Thirty-seven patients with acute myocardial infarction treated with thrombolysis were also enrolled in Holter monitoring to study the course and characteristics of reperfusion arrhythmias (RA). Compared with the non-perfusion group, the total incidence of arrhythmia in both groups was 100%. However, AIVR occurred only in the former, with a rate of 76.2%. The former had sinus bradycardia The incidence of retardation was 42.9%, significantly higher than the latter 12.5%, the difference was significant (P <0.05); the former ventricular arrhythmia occurred within the first 8h after reperfusion Frequent, while the latter without this phenomenon. The author believes that the occurrence of RA has nothing to do with the time of myocardial ischemia, AIVR and transient sinus bradycardia are predictive of reperfusion and inferior wall infarction reperfusion a reliable indicator. Most of the ventricular RA is benign, there is no need for routine antiarrhythmic drugs, but individual patients should still be treated.
