We have often been warned about the risk of dehydration (particularly when travelling) triggering AF but I think that AF causes dehydration so it's something about which we should all be aware. The problem is micturition (urine production)
I am 16 months post-ablation. I have occasional mild AF, the last episode was in June.
On Monday I decided to stay in all day. I wanted to tidy the garden and then make a meal for my son. At 2 pm I was stood by the cooker when my heart flipped and I could feel irregular beating. At 2.30 I took 100 flecainide . Between then and 4pm I produced 4 complete bladder fulls of urine. I was confused as to where it was all coming from and eventually connected my brain and drank 2 mugs of water in addition to my usual tea.
The episode ended at about 4pm leaving me feeling jiggered. I went to bed at 9.30 and slept well until 07.30. In all that time I had not needed a wee so have to conclude that the arrhythmia had left me badly dehydrated.
I hope that this will act as a warning and help in the management of AF episodes.
