To examine whether or not a combination of nonpharmacologic provocative tests potentiated the occurrence of coronary spasm, the cold pressor test combined with hyperventilation was studied in 22 consecutive patients with variant angina admitted to our hospital. After a 12-lead electrocardiogram and blood pressure were recorded, the patient was asked to hyperventilate vigorously at a rate of 30 respirations per min for 6 min under continuous electrocardiographic monitoring.
