As with any cardiac issue, living with AF is different with each patient and your DH should be guided by his Consultant and the clinical team; he will no doubt be assigned a Cardiac Nurse. Personal lifestyle, diet, weight, exercise regime and willingness to make changes all come into the scenario with AF.
This hasn’t applied in my DH’s case, despite asking he has never had specialist advice from a consultant or a specialist nurse. After several episodes of a very persistent rapid heart rate which necessitated visits to A and E he was just prescribed medication by our GP. He was eventually given an echocardiogram after several requests but nobody talked him through the results. We have managed his condition ourselves through research. Cardiac care doesn’t seem to be a strong point in our area, my son’s father-in-law’s family had to push for a heart scan for him, he had a home visit from a GP because he was so poorly but his family still had to press for the heart scan. He had the scan on December 9th, was admitted to hospital immediately because of a badly blocked valve, sadly he was too poorly for surgery and died three weeks ago. I know of other similar cases so good cardiac care isn’t available to everybody, perhaps AF isn’t considered serious enough for access to a consultant or specialist nurse, I don’t know.
