Atrial fibrillation with idiopathic right ventricular outflow tract ventricular tachycardia: A rare combination

Abstract

A 32-year-old lady attended the outpatient door with the complaint of new-onset paroxysmal palpitation for the last 1 month. Her past medical history was not significant. There was no past history of cardiac illness. Her initial 12-lead electrocardiogram (ECG) was within normal limits. While examining the patient, she developed atrial fibrillation (AF) followed by right ventricular outflow tract ventricular tachycardia (RVOT VT). It resolved spontaneously in 2-3 min. AF and RVOT VT are two common arrhythmias having separate mechanisms of onset. Rarely, they can coexist in the same patient. Though uncommon, one tachycardia can act as a trigger for the other. This is known as “tachycardia induced tachycardia or dual tachycardia.”
