摘要
目的:对比分析急性ST段抬高性心肌梗死与非ST段抬高性心肌梗死患者并发心律失常的特点。方法:对明确诊断的213例急性ST段抬高心肌梗死及159例急性非ST段抬高心肌梗死患者发生各种心律失常的性质、特点行对比分析。结果:急性ST段抬高心肌梗死发生窦性心动过缓与室性心动过速的比例明显高于非ST段抬高心肌梗死(P=0.001,P=0.001),而非ST段抬高心肌梗死发生房性早搏与完全右束支传导阻滞比例明显高于ST段抬高心肌梗死(P=0.002,P=0.001);其余各种心律失常的发生率未见有明显差异(P>0.05)。结论:ST段抬高心肌梗死的恶性心律失常的发生率较非ST段抬高心肌梗死高。
Objective:To study the characteristics of arrhythmias in patients with acute ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction(NSTEMI). Methods:Eligible patients were enrolled in the study, including 213 consecutive patients with STEMI and 159 consecutive patients with NSTEMI. Comparative analyses of various kinds of arrhythmias due to AMI were performed by cardiologists other than the ones who were involved in the study,Results:The rates of sinus bradycardias and ventricular tackycardias in patients with STEMI were significantly higher than those in NSTEMI, P=0.001 ,P=0.001 ,respectively, Howere ,the rates of premature atrial complex and complete right bundle branch block(CRBBB) in patients with NSTEMI were markedly higher than those in STEMI, P=0.002, P=0.001, respectively. The rates of other arrhythmias developed due to AMI in the two groups were similar, P〉0.05. Conclusions: In the acute phase of AMI, malignant arrhythmias in STEMI patients are seen more frequently than in NSTEMI patients, which gives contribution to inhospital mortality of the AMI patients. So, much importance should be attached to the arrhythmias developed in STEMI patients and corresponding treatments should be employed in time.
