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 relationship between Tp-e smell and malignant ventricular arrhythmia in patients with coronary heart disease. Methods: A total of 168 patients with coronary heart disease were divided into two groups: the malignant ventricular arrhythmia group (group A, n = 56) and the non-malignant ventricular arrhythmia group (group B, n = 112) The average Tp-e interval, the heart rate correction Tp-e (Tp-e dispersion) interval. Results: Compared with group B The interval between Tp-e interval and Tp-e dispersion of each lead in group A and 12 leads was significantly prolonged (P <0.05 or O.01). Conclusion: Tp-e interval can be used as an index for predicting malignant ventricular arrhythmia in patients with coronary heart disease.
