作者通过研究,提出诊断右心室肥厚的心向量图简化定量标准。这些标准是根据各投影面 QRS环在不同象限的面积分布百分率,并用已证实为右心室肥厚的病例来验证其灵敏度。作者从198名健康人取得正常心向量图,其中20～29岁者50名,30～39岁者50名,40～49岁者50名,50～59岁者48各,均无心血管或肺部疾患,体检、胸部 X 片和心电图均在正常范围。心向量图用 Frank 导联体系。用面积测量术测定三个投面QRS 环在各象限的面积百分率,计算了均值和95% The author through research, put forward the diagnosis of right ventricular hypertrophy of the cardiac vector diagram to simplify quantitative standards. These criteria are based on the percentage distribution of QRS rings in different quadrants of each projection surface and their sensitivity is verified using cases that have been confirmed as right ventricular hypertrophy. The authors obtained a normal cardiogram from 198 healthy individuals, 50 of whom were 20 to 29 years old, 50 of 30 to 39 years of age, 50 of 40 to 49 years of age and 48 of 50 to 59 years of age without cardiovascular or pulmonary Department of disease, physical examination, chest X-ray and ECG are in the normal range. Heart vector diagram with Frank lead system. Area measurements were used to determine the area percentages of three projected QRS rings in each quadrant, with the mean and 95%
