为提高运动试验对冠心病的诊断价值,本文对315例运动试验即刻电轴变化进行分析如下:对象与方法1.对象:冠心病组51例(年龄45～76岁,平均58.8岁),均经内科临床诊断,并根据1979年全国中西医结合防治冠心病研究座谈会修订标准核实。正常组:分中老年组233例,年龄32～76岁,平均52.6岁和青年组31例,年龄16～27岁,平均21.3岁,均经询问病史和体检等未发现心肺疾患者。2.方法:采用活动平板或功率脚踏车,按1979年修订的标准实施。3.测量及评定标准:(1)ST 段均在 J 点后0.08″处测量。下垂型下移,则在 J 点后0.04″处测量。(2)用Ⅰ和Ⅲ导 QRS 波群代数和(取4～6个
In order to improve the diagnostic value of exercise test on coronary heart disease, 315 cases of motor test immediately changes in the axis were analyzed as follows: Subjects and Methods 1. Subjects: coronary heart disease group of 51 patients (aged 45 to 76 years, mean 58.8 years) Clinical diagnosis by internal medicine, and according to the 1979 National Integrative Medicine Coronary Heart Disease Research Symposium to amend the standard verification. Normal group: 233 cases were divided into middle-aged group, aged 32-76 years old, with an average of 52.6 years old and 31 cases of young group, aged from 16 to 27 years old with an average of 21.3 years old. All were asked not to have cardiopulmonary diseases such as medical history and physical examination. 2. Methods: The activity plate or power cycle, according to the 1979 revised standards. 3. Measurement and evaluation criteria: (1) The ST segment is measured at point 0.08 “after point J, while the drooping type is lowered at point 0.04” after point J. (2) with Ⅰ and Ⅲ conduction QRS wave group algebra and (take 4 to 6
