We present the case histories of two patients with angina pectoris who developed coronary artery spasm in response to provocation with prolonged hyperventilation (verified by ST segment elevation in both and coronary angiography in one) despite a negative ECG response to intravenous injection of 0.4 mg ergometrine. This new observation, which is in conflict with recent publications stating that ergot provocation is more sensitive than hyperventilation, suggests that in some patients diagnostic provocation with hyperventilation may be an alternative to the widely used ergot provocation.
我们介绍了两名心绞痛患者的病例史，这两名患者在长时间过度通气激发试验中出现冠状动脉痉挛（两人均通过ST段抬高证实，一人通过冠状动脉造影证实），尽管静脉注射0.4mg麦角新碱后心电图反应为阴性。这一新观察结果与最近的出版物所述的麦角激发试验比过度通气更敏感相矛盾，表明在某些患者中，过度通气诊断激发试验可能是广泛使用的麦角激发试验的替代方法。
