The case of a healthy aviator incidentally found to have an asymptomatic wide complex tachycardia on routine exercise treadmill testing is discussed. Electrophysiologic studies provided the diagnosis of AV nodal reentrant tachycardia (AVNRT) with aberrant conduction. Radio frequency modification of the AV node was performed with good results. Following the procedure, the reentrant tachycardia could not be induced either by repeat electrophysiologic testing or by an exercise treadmill test. The individual was returned to flight status in a restricted capacity.
