Vasospastic ischaemia induced by the hyperventilation test in patients with a negative response to ergometrine.

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.
