摘    要:目的:探讨急性心肌梗死窦性心率震荡(HRT)与发生恶性室性心律失常的关系。方法:入选58例急性心肌梗死患者,计算震荡初始(TO)、震荡斜率(TS)。按室性期前收缩的Lown分级分为观察组28例与对照组30例。根据HRT表现形式(异常及明显异常)分析其与恶性室性心律失常发生的关系。结果:观察组TO 2.52(1.97,3.21)%、TS 0.81(0.39,1.28)ms/RR与对照组TO 1.01(0.46,1.71)%、TS 1.89(1.48,2.12)ms/RR比较,差异均有统计学意义(P<0.05)。HRT明显异常者恶性室性心律失常发生概率(82.35%)明显高于HRT异常者(14.63%)(P<0.01)。结论:急性心肌梗死患者HRT明显异常,发生恶性室性心律失常的概率增高。

关 键 词:急性心肌梗死  窦性心率震荡  恶性室性心律失常

Abstract:Objective To evaluate the relationship between Heart rate turbulence(HRT) and malignant ventricular arrhythmia(VA) in patients with acute myocardial infarction(AMI).Methods Fifty-eight patients with AMI were selected,turbulence onset(TO) and turbulence slope(TS) were calculated.According to the Lown classification of ventricular premature beat were divided into the observation group(n=28) and control group(n=30).The relation of HRT and malignant ventricular arrhythmia(VA) was analyzed according to the HRT manifestation(abnormal and obviously abnormal).Results The observation group TO:2.52(1.97,3.21)%,TS:0.81(0.39,1.28)ms/RR and To:1.01(0.46,1.71)%,TS:1.89(1.48,2.12)ms/RR in the control group,there were signiflcantly different between the observation group and the control group(P0.05).Malignant VA occurred more frequently in patients with obviously abnormal HRT than those with abnormal HRT(82.35% and 14.63%,P0.05).Conclusion The incidence of malignant VA increases with increased obviously abnormal HRT in patients with AMI.
Keywords:Acute myocardial infarction  Heart rate turbulence  Malignant ventricular arrhythmia
