I, too, would certainly be worried about him if I were you. Please know that I had an ablation on 11/24/25 and also had some arrhythymias in a period about three or four weeks afterward, but not A-fib. The APRN I saw for followup stated that it takes 3 months or more before the ablation is considered to be a "failure." (Horrible choice of words--I am a psych nurse and I was really upset with her!) Anyway, you didn't tell us how long he has had A-fib, or how persistent; you also need to know how extensive the ablation was (like just the standard treatment around the pulmonary arteries, or more aggressively looking for foci that trigger the arrhythmias.) You will find that others report ablation failures since it is not a cure, but it is critical, I think, for him to be taking his meds. Can he crush them and put them in water or juice? Is he trying any supplements like Magnesium that would help to stabilize the arrhythymias? Didn't the EP doc schedule a follow-up appointment at 6 weeks and 3 months? Mine did and I thought that would be the standard for care. As for the legs, that is most certainly a circulation problem and should not go ignored. If he has diabetes, does he follow a routine to check his blood sugars regularly. Even though we are not diabetic, my husband and I check our blood glucose levels regularly on our own. You can get a glucometer at any drug store; they are not expensive. I know that there are many people who hate to go to the doctor or are fearful, but if he is still working then he is too young to give up on his health. Make him an appointment and go with him; insist that the doctor answer your questions! I can assure you that if you don't get assertive, you won't get the help he needs. I have a husband that sounded like yours, but I have really gotten him to be more pro-active and he is doing better and he is 80 years old. I just want you to feel supported. Please keep after him; there are ways to make this better. As for the trip coming up, I would seriously suggest not going unless he gets some treatment. Nothing is worse than being ill a long way from home. (We were stuck in France on vacation for 30 days due to a bike accident that my husband had; it was very challenging to say the least.) Good luck to you both, sincerely!
