A case of adenosine-sensitive ventricular tachycardia in a very elderly male.
The best-known type of adenosine-sensitive ventricular tachycardia is idiopathic and of right ventricular outflow origin; however, there is little information about other types of adenosine-sensitive ventricular tachycardia. Idiopathic adenosine-sensitive ventricular tachycardia is common in the young. An 87-year-old man with ventricular tachycardia was admitted to our hospital. His ventricular tachycardia was sensitive to adenosine triphosphate, edrophonium, verapamil, and Valsalva's maneuver. He had experienced no anginal episodes. His ventricular tachycardia was thought to be idiopathic. We report this very rare case of adenosine-sensitive ventricular tachycardia, which was not derived from the right ventricular outflow tract, in a very elderly male.
