Two cases of acute pulmonary edema following iv administration of metaraminol for the treatment of paroxysmal supraventricular tachycardia are described. One of the patients was a young girl with Wolff Parkinson White syndrome and no demonstrable myocardial disease. The sudden rise in systemic blood pressure and an inability of the left ventricle to overcome the sudden increase in its afterload was presumed to be the mechanism responsible for the acute left heart failure. It is recommended that patients undergoing iv metaraminol therapy for supraventricular tachycardia be carefully monitored for an exaggerated rise in blood pressure or further abnormalities of cardiac rhythm, and carefully watched for early signs of left ventricular failure.
