心向量图定标电压的测量方法有直角边法和对角线法两种,二者所得向量振幅数值不同,使诊断标准不好掌握。我们对200名正常人(男110名,女90名,年龄20～73岁,进行体检与胸部X-线检查,排除了心、
Heart vector map calibration voltage measurement methods are two kinds of right-angle method and diagonal method, the two vector amplitude values are different, so that the diagnostic criteria is not good grasp. We examined 200 normal subjects (110 males and 90 females, aged 20-73 years, with physical examination and chest X-ray examination, excluding the heart,
