3-Dimensional Mapping System: The PULSTAR Study

"Routinely placing a coronary sinus electrode catheter, puncturing the interatrial septum, placing one sheath into the left atrium, confirming that the catheter is well in place, and setting the treatment time of the pulse ablation system in advance.~Pulmonary vein-by-pulmonary vein ablation using a circular pulse catheter, waiting for the end of the pulse ablation phase and immediate effect confirmation."
