Digitalis and Ventricular Tachycardia. Digoxin was used to treat a patient with an adenosine‐sensitive ventricular arrhythmia. The patient had an exercise‐induced ventricular tachycardia that was evaluated electrophysiologically and displayed characteristics of a triggered arrhythmia. The tachycardia was terminated reproducibly with 12 mg of intravenous adenosine. After treatment with digoxin (serum level = 1.7 ng/mL), the arrhythmia could no longer be initiated with programmed electrical stimulation or exercise treadmill testing. The patient has since remained symptom free for 10 months. The autonomic effects of digitalis are proposed to mediate drug efficacy in this form of ventricular tachycardia.
