The findings of coronary angiography, ventriculography and bicycle ergometry were compared in 64 patients with coronary heart disease and asynergic zones in the left ventricle. An increase in the sum of the amplitudes of R waves of the ECG during the exercise test generally combined with a displacement of the ST segment was predominantly observed in patients with asynergies of ischemic genesis. By contrast, in patients with asynergies secondary to post-infarction cardiosclerosis, an elevation of R waves during bicycle ergometry cannot be a reliable sign of coronary failure, yet it permits the identification of individuals with marked disorders of the contractile function of the left ventricle.
对64例冠心病且左心室存在无运动区的患者的冠状动脉造影、心室造影和自行车测力计测试结果进行了比较。运动试验期间心电图R波振幅总和增加且通常伴有ST段移位，这主要见于缺血性起源无运动的患者。相比之下，在心肌梗死后心肌硬化继发无运动的患者中，自行车测力计测试期间R波升高并非冠状动脉功能不全的可靠征象，但它有助于识别左心室收缩功能明显紊乱的个体。
