Exercise-induced ventricular tachycardia can be a rare manifestation of digitalis toxicity.
Alerts clinicians to rare exercise-only digitalis VT; extends known toxicity manifestations but remains hypothesis-generating.
Digitalis intoxication is one of the most common adverse drug reactions. Although some arrhythmias are seen more frequently than others, virtually any rhythm disturbance, including ventricular tachycardia, may occur. However, to our knowledge, exercise-induced ventricular tachycardia as a complication of digitalis therapy has never been described before. This case presents a patient with a digitalis-induced ventricular tachycardia occurring exclusively during exercise.
