目的:探讨心电图(ECG)V1,5导联T波的特征及V6导联T波和R波的特征;TV1/T v5>1,V6T/R<1/10在冠心病的诊断及预后评价中的作用。方法:分析150例因胸部不适而接受冠状动脉造影(CAG)患者的心电图TV1/T V5>1,V6T/R<1/10阳性率在CAG阳性及阴性组中的差异,以及随访观察CAG阳性患者中冠状动脉(简称冠脉)事件发生率。结果:TV1/T V5>1,V6T/R<1/10阳性率在CAG阳性组和阴性组中分别为54.0%,14.1%,两者间差异显著(P<0.01);在CAG阳性患者中,有TV1/T V5>1,V6T/R<1/10阳性患者冠脉事件发生率高于TV1/T V5>1,V6T/R<1/10阴性患者。结论:对于胸部不适的患者,心电图T V1>T V5,6阳性可提示冠脉存在病变,并可预示在CAG阳性患者中,有TV1/T V5>1,V6T/R<1/10阳性其冠脉事件发生率高。
PURPOSE: To investigate the characteristics of T wave of lead V1 and lead 5 in ECG and characteristics of T wave and R wave in lead V6. The diagnostic and prognostic value of TV1 / T v5> 1 and V6T / R <1/10 in coronary heart disease In the role. Methods: The electrocardiogram TV1 / T V5> 1 of 150 patients with coronary artery angiography (CAG) who had chest discomfort were analyzed. The positive rates of V6T / R <1/10 in CAG positive and negative groups were analyzed. The incidence of coronary events (referred to as coronary events) in patients. Results: The positive rates of TV1 / T V5> 1 and V6T / R <1/10 were 54.0% and 14.1% respectively in CAG positive group and negative group (P <0.01). In CAG positive patients . The incidence of coronary events in TV1 / T V5> 1 and V6T / R <1/10 positive patients was higher than that in TV1 / T V5> 1 and V6T / R <1/10 negative patients. CONCLUSIONS: In patients with chest discomfort, the positive ECG T V1> T V5,6 may indicate the presence of coronary artery lesions and may indicate that in CAG-positive patients, TV1 / T V5> 1 and V6T / R <1/10 are positive High incidence of coronary events.
