冠心病患者心电图PTFV_1与左室舒张功能的相关分析

A study of relationship between PTFV_1 of ECG and left ventricular diastolic function in patients with CHD

目的:探讨冠心病患者心电图V1导联P波终末电势(PTFV1)与左室舒张功能的关系。方法:应用超声心动图和心电图对40例冠心病患者和38例健康人进行分析。结果:①冠心病患者左室舒张功能指标左室舒张早期二尖瓣血流峰值速度/左室舒张晚期峰值速度(E/A)与正常对照组存在显著性差异;②冠心病患者心电图PTFV1负值大者E/A比值显著降低;③冠心病患者心电图PTFV1与舒张功能指标E/A值存在正相关(r=0.52,P<0.01)。结论:心电图PTFV1有助于评价左室舒张功能的障碍。

Objective ：To investigate the relationship between PTFV1 of ECG and left ventrieular diastolic function in patients with CHD. Methods： 40 patients with CHD and 38 healthy people were examined by eehocardiography and ECG. Results： ①The differences of A/E between two groups were statistically significant; ②The larger the negative number of PTFV1 of ECG in patients with CHD, the greater decrease of the A/E;③PTFV1 correlated positively to the ME （r=0.52, P〈0.01）. Conclusion：There are positive correlation between PTFVI of ECG and left ventrieular function, PTFV1 can help to access the left ventficular function.
