Hello. I am new to this site and I have had AF for 2 Years now. I had an Ablation operation 3 weeks ago and although my AF has lessened a lot i still have the same problem of feeling hot and dizzy when i stand still for a short time. This is really affecting my life and I don't seem to get any answers from my doctor or cardiologist, they just say you do get dizzy with AF. I can't go shopping or out anywhere if there are queues or it is busy as when i have to stand still i start to feel ill and have passed out on a few occasions. I am wondering if it is the AF that is causing this or the medication i am on. It is so bad i have had to give up my job as i am meant to be on my feet alot. I would appreciate anyone letting me know if they have similar problems.
