I'm hoping someone here might be able advise on exercise for people with AF.
My background is: I am 55 years-old, had a heart attack 4-years ago (stent inserted); AF a year later; another fast AF a couple of months ago.
I was admitted to A&E, and after 12-hours was restored to sinus rythmn after lots of Bisoprolol. The A&E dept. referred me to Cardiology for follow-up and ECG, but sadly, Watford General Hospital Cardiology says that AF does not reach their 'threshold' for a follow-up consultation, and when my GP tried again, they 'declined' his referral. He is honest enough to admit that he is not a cardiology specialist. So, it's up to me, Dr Google, and my friends in this forum.
All I was told by the hospital was that it's important to resume exercise, but to not 'overdo it', and if I feel unwell I should stop. That latter point doesn't really help because with heart disease I feel unwell most of the time!
My exercise regime is a 30-minute session on an exercise bike, 5-times a week. I divide the session into 3 periods of 10-minutes: a slow warm-up, intensive middle period, then 10-minutes slowing down to end. I increase the resistance setting on the bike as I approach the middle 10-minutes, then decrease back down to easy towards the end. I try to then do 5-minutes of breathing exercises, and drink some water.
My resting pulse is usually below 50bpm (due to taking 1.25mg daily of Bisoprolol, I suppose), so I am scared to push myself above 100bpm during exercise. I probably average 90bpm during most of the session. My PI can reach 30%, and my O2 sats sometimes 100%. My blood pressure at rest is usually 120/80, slightly higher after exercise.
Am I doing too much, or too little? Is the exercise bike considered useful exercise, or am I a lightweight? Any advice welcome.
