I Had My Second Catheter Ablation Two Days Ago. This

I had my second catheter ablation two days ago. This time the doc told me gave some adrenaline to trigger afib to see where to aim to relieve of my occasional afib episodes. He found some cell around one of the major pulmonary veins that he treated. Then gave me 200 Joules to get me back in sinus r. Is this a normal
treatment? I would like to know the best minerals, proteins and other suppliments to heal fast naturally and help this be a successful last ablation.
