Beta-adrenergic blockade in the treatment of exercise-induced paroxysmal ventricular tachycardia



Beta-adrenergic blockade in the treatment of exercise-induced paroxysmal ventricular tachycardia



Circulation 32(5): 778-781



Paroxysmal ventricular tachycardia was provoked by minor exertion in a young male without evidence of structural heart disease. Intravenous pronethalol prevented the appearance of the arrhythmia with exertion and oral pronethalol 100 mg 3 times daily produced almost complete suppression over a treatment period of 6 months. This arrhythmia is considered to result from an abnormal response to adrenergic stimuli. The effectiveness of pronethalol may be particularly related to its beta-adrenergic blocking activity but pronethalol also has other properties common to other antiarrhythmic drugs.
