摘要
为探讨心肌缺血（Mi）与心室复极离散度增加和室性心动过速（VT）的关系，对冠心病Mi时伴VT（22例）与无VT（NVT，35例）患者和见例健康人心室复极各参数对比分析后发现：（1）VT组和NVF组QT和JT间期各参数均明显长于对照组（P＜0.01），而VT组的QTd、QTcd、JTd和JTcd又明显长于NVT组（P＜0．01）；（2）VT组与NVT组比较，VT组Mi总时间长，Mi阵次高以及全程呈持续性Mi的发生率高（P值均＜0.05）；（3）VT组室早总数和3级以上室旱总发生率均高于NVT组（P＜0.05），尤其是成对室早（P＜0.005）。结果表明：冠心病患者中VT可能与Mi致心室复极离散度增加有关。
To study the relationship between increaseddispersion of ventricular repolarization induced by myocardialischemia(MI) and ventricular tachycardia(VT) in patients with coronary heart dsease (CHD). This study have investi gated the ventricular repolariztion parameter of cases of MIwith VT (VT group), 35 cases of MI without VT (NVTgroup in the parients with CHD and 40 cases of healthyadults.The results showed: (1)Not only did QT、JT interval parameter in the VT and NVT group increas markedlythan those of control group (P< 0.01); but also QT、QTc dispersion and JT、JTc dispersion in the VT group grew more markedly than those of the NVT group(p < 0.01 ); (2)Compared with the NVT group the total time of MI、 the dailynumber of MI epison the incidence of sustained MI weresignificantly higher in the VT group (P < 0.05); (3) Boththe total number of the ventricular premature complexes(VPC) and the of VPC that were grade Ⅲ or higher were greater in the VT group than thos in the NVT group (P<0.05), especially, so were the couplets VPC (P< 0.05). This results suggested that the VT were related to thedispersion of ventricular repolarization induced by MI the patients with CHD.
