作者对20例行心导管检查的患者在静息和运动状态下进行右室造影,以估价运动和冠脉病变对右室收缩功能的影响。13例患者造影片质量良好可供分析,并被分为二组。A 组无或仅有轻微冠脉病变。B 组则有明显的冠脉病变:运动诱发新的左室局部室壁运动异常。运动状态下,A、B 两组右室收缩压 The authors performed a right ventriculography of 20 patients undergoing cardiac catheterization at rest and with exercise to assess the effects of exercise and coronary lesions on right ventricular systolic function. Thirteen patients made the films of good quality for analysis and were divided into two groups. Group A had no or only mild coronary lesions. Group B had obvious coronary lesions: exercise-induced new left ventricular local wall motion abnormalities. Exercise, A, B right ventricular systolic pressure
