心电图诊断左房增大常以二尖瓣P波为诊断依据。近年来PV_1终末电势(PtfV_1)与左房增大、左心功能不全的关系也已经引起临床工作者的重视。我们通过超声心动图检查,结合临床和心电图,以分析PtfV_1与左房增大、左心功能不全之间的关系,现将资料完整的61例分析报告如下。1 临床资料 根据PtfV_1值分为两组,PtfV_1(>-0.
ECG diagnosis of left atrial enlargement often based on mitral P wave diagnosis. In recent years, PV_1 terminal potential (PtfV_1) and left atrial enlargement, left ventricular dysfunction has also attracted the attention of clinicians. We through echocardiography, combined with clinical and electrocardiogram, to analyze the relationship between PtfV_1 and left atrial enlargement, left ventricular dysfunction, the data are complete 61 cases of the following report. 1 clinical data according to the PtfV_1 value is divided into two groups, PtfV_1 (> - 0.
