The Best Workflow for Paroxysmal Supraventricular Tachycardia Ablation With Zero-fluoroscopy

Primary Objective: To observe, record, and analyze the workflow and guidance system efficiency of these two surgical procedures, including placement time, location, and the number of successful placements. Secondary Objective: To compare the differences between the two procedures and observe and record the process of transitioning to intracardiac ultrasound guidance by experienced physicians performing both workflows. The primary focus is on the time spent on target steps and related complications, with the aim of reducing radiation exposure during the procedure with the new technology.
