Thx for your timely comment.
My husband was taking Diltiazm prior to Amiodarone after ablations. Altho he is still Afib and flutters, his fatigue was gone immediately after ablation. He is now taking CCB Norvasc for BP.

Next is either another ablation, rate control, pacemaker. While leadless pacemaker is a good option for my husband’s single-chamber ventricular pacing due to slow heart rate, this new pacemaker that can follow the patient’s body clock is interesting.
