case_images: A pulsed field ablation catheter was positioned within the superior vena cava, revealing the disorganized electrical activity. The intracardiac electrocardiogram was recorded at a speed of 100 mm/s.

case_images: The circular pulsed field ablation catheter was then placed within the superior vena cava, revealing some brief fractionated potentials and a local atrial fibrillation cycle length shorter than that in the coronary sinus (Figure 1).
case_images: The atrial fibrillation terminated after the pulsed field ablation catheter discharged at the superior vena cava. The electrocardiogram was recorded at a speed of 100 mm/s.
