ABSTRACT

A 54-year-old female with recurrent syncope was referred to our institution for electrophysiological study. The patient had two documented intolerable tachycardia; one of them was a wide QRS, and the other one was a narrow QRS. As a clinical puzzle format, we aimed to present our basic electrophysiological approach of an intolerable and rare clinical tachycardia.
