对运动心电图△R标准临床意义和R波振幅变化机理的研究,目前是一个比较活跃的课题。本文拟就国内外有关这方面研究的概况结合作者的体会作一简介。一、△R标准的提出运动心电图R波振幅变化的意义早已引起一些学者的注意。Simoons在1953年就报道正常人运动后R波振幅降低。Kentala等在1973年提议把运动心电图R波振幅的变化作为衡量
The study on the clinical significance of △ R standard and the mechanism of R-wave amplitude changes of exercise ECG is currently an active topic. This article intends to make an introduction to the general situation of the research in this field at home and abroad with the author’s experience. First, the △ R standard motion ECG R wave amplitude changes have long been the significance of some scholars. In 1953, Simoons reported normalized R wave amplitudes after exercise. Kentala et al proposed in 1973 the change of the amplitude of R wave of exercise ECG as a measure
