PROCEDURE

Invasive Electrophysiology Study

Invasive electrophysiology studies will be performed using four catheters placed in the right ventricular apex, the coronary sinus, the His bundle region, and the high right atrium. Standard induction protocols for supraventricular and ventricular arrhythmias will be utilized in the absence and presence of isoproterenol. Long-short ventricular extra-stimuli will also be delivered to screen for bundle branch reentrant ventricular tachycardia. The study is considered observational as the participating sites perform electrophysiology studies in this patient population as part of standard clinical care.
