AF Association

Micturation and AF - the reason?

Some time ago we had a discussion (with some hilarious posts) about frequent loo visits to pee during AF and it was a question which I put during a consultation but didn't get an definitive answer.

I had a recent run of SVT episodes and the same trotting to the loo occurred. Apparently it is because of ANP (Atrial Natriuretic Peptide) which controls body water, sodium, potassium and some other chemicals and is released by the stretching of the atria. The atria are stretched by (amongst other things) blood volume during AF and SVT.

So, the next time you need to fill and refill the commode folks, blame ANP!

"Urination is the release of urine from the urinary bladder through the urethra to the urinary meatus outside of the body. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including tinkling, peeing, weeing, and pissing."

I copied this from Wiki-pee-dia :-)


Aww hee hee, I needed that definition. Wiki-pee-dia forsooth!


So now we know! It's still happening - vast volumes. Funnily there ie no warning that it might start - you'd think that you hardly produced anything prior to all this production but it doesn't seem to work like that! I still laugh when I think about those original posts!


I will never remember that. I will probably end up blaming the ANC instead and being banned from South Africa.



Koll you made me laugh out loud with your Wiki-pee-dia description of urination.

It was the one thing I found distressing when attending A&E, I was on and off the trolley like a yo-yo, but now I fully understand what is happening, I will take it all in my stride!!!!

What ever causes it; it can be dangerous. Before I was diagnosed with Afib, I would get up at night and fill and refill my faithful commode and the next morning faint before breakfast. The clinic said I was dehydrated but in reality I was in Afib.

Fortunately I didn't break any bones.



Been there done that! :))


I'm REALLY pleased you posted this! Yes, it is a matter for hilarity, but not at 6am when you have been going every 40 mins since 11pm, and producing 650-750 ml each time. I don't know if I should drink more during the night, or the following day, or not bother. My GP told me that it was just coincidental, and I had 'obviously' drunk too much the previous evening. I'm Sure I'd remember an extra 7 litres or so..... but maybe Atrial Fibrillation causes amnesia, and dipsomania immediately before it has an episode!


Is it just me that notices extreme thirst also along with the loo visits?

When I was in last time at 37 weeks pregnant they would not let me off the bed to pee. I ended up having to use one of those cardboard things and balance my girth, ecg cables and hospital gown on a hospital trolley and pee! Very undignified and wobbly. Luckily I did not spill any LOL.
