My story. I have been training for Ironmans on and off since 1990 and have never had any health related issues. I have not always eaten well and thru the early 2000 raised 2 kids ( with my wife) so training was inconsistent. Started back training consistently in 2016 using a polarized model but the last few yrs spent more and more time in the pool while keeping the same bike, run ,gym volume. The month leading up to Thursday were high volume swimming and increasing in Swim ,bike ,run ,gym hours. The A fib started after the swim session when my wife and I were sitting for breakfast and it lasted 12 hrs ,i did see a medical professional and am in line for a ECG but that will probably show little of why it happened. From the what I have been reading and what I have listened too this is what I have come up with. Inflammation is a probable cause ,a large volume of work with little recovery ,high carb diet , too much caffeine , using fish oil supplements are all things I did that I think triggered this event. This below is a 2 part podcast with a person who has gone thru it and researched AF its very interesting.
So if anyone has had it or itâ€™s a ongoing issue I would love to hear your take on your experiences.
All the best.
