We have seen a case with spasm of the right coronary artery coming on during exercise ergometry in the course of a coronary arteriogram. The patient had angina pectoris spontaneously and on exercise. Bicycle ergometry was repeated four times by the same method, and was positive in three; in two of these there was angina and ST elevation in II, III, aVF, and ST depression in I, aVL and V2 to V5. On one occasion the test was negative, the patient having taken a trinitrin tablet one hour before the test. Repeating the exercise test during coronary arteriography showed spasm of the right coronary artery and elevation of the segment ST in II, III and aVF; this disappeared after trinitrin treatment.
我们曾遇到过一例在冠状动脉造影过程中进行运动负荷试验时出现右冠状动脉痉挛的病例。该患者在静息及运动时均有自发性心绞痛。采用相同方法重复进行了四次自行车运动负荷试验，其中三次结果为阳性；在其中两次试验中，患者出现心绞痛，Ⅱ、Ⅲ、aVF导联ST段抬高，Ⅰ、aVL及V2至V5导联ST段压低。有一次试验结果为阴性，该患者在试验前一小时服用了一片硝酸甘油。在冠状动脉造影期间重复进行运动试验显示右冠状动脉痉挛，Ⅱ、Ⅲ及aVF导联ST段抬高；经硝酸甘油治疗后上述情况消失。
