Official Title: Intracardiac Echocardiography Guided vs. Electroanatomical Mapping System Guided Slow Pathway Ablation in Patients With Atrioventricular Nodal Reentrant Tachycardia
Brief Summary:
Study protocolTo prepare for the electrophysiologic study, antiarrhythmic drugs were discontinued at least five half-lives before the procedure and were under conscious sedation using midazolam ± fentanyl while fasting.ICE-guided ablation group In patients randomized to ICE-guided ablation group, catheter placement was initially performed using fluoroscopy guidance, after local anesthesia.A decapolar steerable catheter was placed in the coronary sinus (CS), a quadripolar electrode catheter was positioned in the…
