I've been a super keen sportsman for the last 40 years and by most standards am extremely fit and healthy (I'm now 60).
I have also had odd bout of AF for about the same time. Over the least 10 years these bouts have become more frequent and it now happens once a week and for about 1 to 2 days. These are without symptoms -- for example there is no change to my heart rate and I've happily done a 15 mile mountain walk during an episode. But the episodes are emotionally very hard for me and I can get pretty down about it.
Over this time I haven't found anyone who can give me any advice so I thought I'd try here and also share my experiences.
I have found that the following are the key triggers that bring AF on: - 1) Getting dehydrated (so I now drink a lot); 2) Taking a cold drinks (never take an iced drink and NOT from the tap in winter -- it must be tepid. This is especially important if your hydration levels are getting low); 3) Low salt levels -- so I eat crisps and other salty snacks as well as using sports drink tablets and especially after exercise or in hot weather; 4) No sudden bursts of exercise (running hard without warming up -- and I now avoid flat out exercise too)
I have found that a long strenuous cycle ride (>30 Minutes and a lot of uphill) will usually induce a return to sinus rhythm
No-one told me any of this -- i Just found it out by experimentation. And some of this goes against the prevailing wisdom, so I wanted to share it in case it helps anyone else. And I would appreciate any other advice others can give.
(PS I only use medicine sparingly and as a last resort)
