Coronary hypertonia was observed in a patient with unstable angina. It was possible on one occasion to reproduce the clinical picture, electrocardiographic changes, lactate production and coronary hypertonia by means of atrial pacing. He had a normal left coronary arteriogram when the diffuse spasm was relieved by nitroglycerin. Therefore hypertonia (or spasm) of the left coronary artery was believed to be the cause of his variant angina with subendocardial ischemia.

在一名不稳定型心绞痛患者中观察到冠状动脉张力过高。有一次，通过心房起搏能够重现临床症状、心电图变化、乳酸生成及冠状动脉张力过高的情况。当硝酸甘油缓解弥漫性痉挛时，他的左冠状动脉造影显示正常。因此，左冠状动脉张力过高（或痉挛）被认为是其伴有心内膜下缺血的变异型心绞痛的病因。
