Refractory Ventricular Tachycardia
P.W. is a 57-year-old white man who was in good health until 1972, when he suffered an acute anterior myocardial infarction. His immediate postinfarction course was uncomplicated. He did well for the next two years, when he then began to have symptoms of progressive dyspnea and fatigue. Subsequent physical examination revealed a systolic murmur, and further evaluation proved this to be severe calcific aortic stenosis. He underwent aortic valve replacement in March of 1978 with a Starr-Edwards prosthesis. At this time he developed intraoperative and postoperative runs of ventricular tachycardia (VT). He was treated with propranolol and quinidine with resolution of the arrhythmia. The medications were discontinued after discharge as the rhythm disturbance was felt to be related to the stress of the operative procedure.
