作者研究了正常人和不同原因引起的右室负荷过重病人(RVO)的U向量环形状及定量特征,结果表明U环异常是诊断RVO的一个较好指标,并对理解RVO患者心电图的异常有所帮助。方法正常对照组126例,血压、心电图、胸透等检查正常,均无心脏病、肾脏病或糖尿病史;RVO组58例,其病因为房间隔缺损39例、二尖瓣狭窄12例、法乐氏四联症3例、肺动脉狭窄2例、原发性肺动脉高压2例。还检查了完全性右束支传导阻滞(CRBBB)15例。
The authors studied the shape and quantitative characteristics of U vector rings in RVO patients caused by normal subjects and different causes. The results showed that U-ring abnormalities were a good indicator for the diagnosis of RVO and were helpful to understand the abnormality of electrocardiogram in RVO patients Help Methods 126 cases of normal control group, blood pressure, electrocardiogram, chest X-ray and other tests were normal, no heart disease, kidney disease or diabetes history; RVO group of 58 cases, the cause of atrial septal defect in 39 cases, mitral stenosis in 12 cases, Tetralogy of Fallot in 3 cases, pulmonary stenosis in 2 cases, 2 cases of primary pulmonary hypertension. Fifteen patients with complete right bundle branch block (CRBBB) were also examined.
