Abstract
A man with a history of remote myocardial infarction developed refractory recurrent tachyarrhythmia with widened QRS complexes. Conversion to sinus rhythm during administration of intravenous vasopressors occurred on several occasions, and the arrhythmia was considered to be supraventricular tachycardia with aberration of the QRS. Atrial recording, competitive atrial pacing, and Holter monitoring were used to establish a diagnosis of ventricular tachycardia. Subsequent to coronary artery bypass surgery and partial excision of a noncontractile scar from the posterior wall of the left ventricle, he has had no further tachyarrhythmias. The difficulties in differential diagnosis and the techniques used are discussed.
