总结81例冠状动脉粥样硬化性心脏病患者心电图 V_1导联终末电势(PTFV_1)的检测结果,以≤-0.03mm·s 作为阳性标准,并与冠状动脉造影及左室造影结果对比分析,显示 PTFV_1的阳性率与冠脉狭窄程度密切相关,狭窄程度越重,阳性率越高。且 PTFV_1值越小,左室射血分数越小,左室舒张末期压力越高。故 PTFV_1值的大小在一定程度上反映了左室功能损害的严重程度及冠脉病变程度。
Conclusions 81 patients with coronary atherosclerotic heart disease ECG V_1 lead terminal potential (PTFV_1) test results, ≤ -0.03mm · s as a positive standard, and coronary angiography and left ventricular angiography results were analyzed, It showed that the positive rate of PTFV_1 was closely related to the degree of coronary stenosis. The more stenosis, the higher the positive rate. And the smaller PTFV_1 value, the smaller the left ventricular ejection fraction, the higher the left ventricular end-diastolic pressure. Therefore, the size of the PTFV_1 value reflects to some extent, the severity of left ventricular dysfunction and coronary lesions.
