A case of a 42-year-old woman who had combined sinus and atrioventricular nodal tachycardia is reported. Programmed atrial stimulation study showed the induction of the two types of paroxysmal supraventricular tachycardia. The mechanisms of these supraventricular tachycardias were both sinus nodal and atrioventricular re-entrant tachycardia. Sinus nodal reentrant tachycardia could be induced only after injection of atropine. The tachycardias could no longer be induced after the administration of verapamil.
