Tonight’s rant about Denmark Euro game.

[Brandane]

I was very ill in 2012/13 and ever since then I have been able to put my heart into arrhythmia by excessive physical efforts. I'm okay up to (say) 90-95% effort but that last 5-10% can set it off.

So far it has been just an unpleasant random 'fluttering', but it can go on for hours, or even over a day sometimes.

I am assuming that with your history of blood clots, you have had this arrhythmia checked out? I ask because I have an atrial fibrillation, an on-going thing for the last 25 years or so. I take 2 pills per day and it is fine, but even so I am careful with exercise. Or to put it another way, I don't even attempt to compete with other cyclists and keep at my own leisurely pace.
When I was diagnosed with the AF, I was told that my heart was healthy, it was just the timing of it's beating that was out. Not a problem on it's own, they said, but if left unchecked the AF can cause blood clots, and you will know the possible consequences of that....
