Key result
A 73-year-old man with rare exercise-induced uncommon atrioventricular nodal reentrant tachycardia and sick sinus syndrome was successfully treated with verapamil and DDD pacing for 5 years.
Case Report (n=1)
Exercise-induced uncommon AVNRT with sick sinus syndrome is a rare presentation that can be successfully managed with a combination of verapamil and DDD pacing.

May support verapamil plus DDD pacing in rare exercise-induced AVNRT with SSS; hypothesis-generating and requires prospective confirmation.
Exercise seldom provokes tachycardia in patients with paroxysmal supraventricular tachycardia (PSVT). This report presents a case of exercise-induced uncommon atrioventricular nodal reentrant tachycardia (AVNRT) with sick sinus syndrome. Treadmill exercise testing provoked AVNRT of long RP' with good reproducibility. Uncommon AVNRT was confirmed by the lack of atrial pre-excitation during PSVT and para-Hisian pacing. The patient has been successfully treated with verapamil and DDD pacing for 5 years.

Komori et al. (1999) conducted a case report in Exercise-induced uncommon atrioventricular nodal reentrant tachycardia with sick sinus syndrome (n=1). Verapamil and DDD pacemaker was evaluated on Prevention of paroxysmal supraventricular tachycardia. A 73-year-old man with rare exercise-induced uncommon atrioventricular nodal reentrant tachycardia and sick sinus syndrome was successfully treated with verapamil and DDD pacing for 5 years.
