恶性室性心律失常与Tp—e间期关系的探讨

Malignant ventricular arrhythmias and Tp-e interval relations of

目的:探讨Tp—e闻期与冠心病恶性室性心律失常的关系。方法:对168例冠心病者分为恶性室性心律失常组(A组,n=56)和非恶性室性心律失常组(B组,n=112),比较两组各导联和12导联平均Tp一e间期、经心率校正的Tp一e(Tp—e离散度)间期。结果:与B组比较。A组各导联和12导联平均Tp一e间期和Tp—e离散度间期显著延长,差异有统计学意义(P<0.05或O.01)。结论:Tp一e间期可作为预测冠心痛恶性室性心律失常的指标。

Objective To investigate the period Tp-e heard of malignant ventricular arrhythmias and coronary heart disease relationship.Methods 168 cases of coronary heart disease were divided into malignant ventricular arrhythmia group（A,n = 56） and nonmalignant ventricular arrhythmia group（B,n=112）,compared two groups of lead and 12 lead average Tp-e interval,the heart rate corrected Tp an e（Tp-e dispersion） interval.Compared with group B results.A group of 12-lead and lead the average period between Tpe dispersion and Tp-e interval was significantly prolonged,the difference was statistically significant（P0.05 or O.01）.Conclusion Tpe interval may be as a predictor of coronary heart indicator of malignant ventricular arrhythmias.
