To evaluate the influence of an exercise program on spatial and left precordial R-wave amplitude among patients with coronary artery disease, computerized electrocardiogram (ECG) data were acquired during maximal treadmill testing before and after 1 yr in 89 patients randomized to either exercise (n = 40) or control (n = 49) groups. Spatial and lateral R-wave amplitudes were derived from the orthogonal Frank (XYZ) lead system. The exercise group significantly increased maximal O2 consumption (0.17 l/min), whereas controls decreased significantly (0.12 l/min, P less than 0.01 between groups). No significant changes in electrocardiographic R-wave voltage measurements occurred within or between groups during the year. It is concluded that exercise training does not result in increases in R-wave voltage in patients with coronary artery disease.
为评估运动计划对冠心病患者空间及左胸前区R波振幅的影响，在最大运动平板试验期间，对89例随机分为运动组（n = 40）或对照组（n = 49）的患者，于1年前和1年后采集了计算机化心电图（ECG）数据。空间及侧壁R波振幅由正交Frank（XYZ）导联系统得出。运动组最大摄氧量显著增加（0.17升/分钟），而对照组显著下降（0.12升/分钟，两组间P<0.01）。在这一年中，组内或组间心电图R波电压测量均未发生显著变化。结论是，运动训练不会导致冠心病患者R波电压升高。
