急性心肌梗死再灌注心律失常与心室复极离散度的关系

THE RELATIONSHIP BETWEEN REPERFUSED ARRHYTIHMIA AND VENTRICULAR REPOLARIZATION DISPERSION IN ACUTE MYOCARDIAL INFARCTION

为探讨再灌注心律失常与心室复极离散度的关系，对急性心肌梗死溶栓患者（３１例）再灌注前、后和未溶栓患者（３４例）间进行心室复极各参数对比分析后发现：溶栓再通组的ＱＴｄ，ＱＴｃｄ，ＱＴ１ｃｄ，ＪＴｄ，ＪＴｃｄ及ＪＴ１ｃｄ明显长于溶栓前、未再通组和未溶栓组（Ｐ＜０．０１），再通组室性心律失常明显多于未溶栓组（Ｐ＜０．０１）；前壁心肌梗死再灌注组的ＱＴｄ长于下、后壁组（Ｐ＜０．０５），而前者的ＱＴｃｄ、ＱＴ１ｃｄ则明显长于后者（Ｐ＜０．０１）。结果表明：再灌注后室性心律失常的多发和心室复极离散度增加有关。

In order to asxss the relationship between reperfused arrythmia and ventricular repolarization dispersion (VRD) , 31 patients with a- cute myourdial infarction ( AMI) treated by intravenous tluombnlysis were studied. Thirtytfour patients that were not treated by intra- venous thrambolysis served as the control group. Electrocardiogram (ECG) parmeters were measured and compared. The values for QTd , QTcd,QTlcd,JTd,JTcd and JT1cd in the reperfused group were significantly greater than in the pretthrombolytic, non-reperfused and non-thrombolytic groups (P<0.01). Reperfused ventricular arrhythmia (RVA) was significantly greater in the reperfused group than in the non-thrombolytic group (P<0. 01) . Similarly, increased QTd (P<0. 05) and significantly increased QTcd, QT1cd (P<0. 01) were noted in patients with anterior venus those with inferior, lateral AMI . The results suggest that greater RVA is asociated with higher VRD .
