Hi Kathleen - thanks so much for your post. The A-Fib palpitations made me feel really unwell, cold sweat, very weak, freezing cold (literally my teeth chatter), dizzy , pounding fluttering fast heart and feel unwell for quite a while after they stop (at the moment they are only paroxysmal thankfully but I understand can become all the time hence the need for an ablation and beta blockers). The palpitations I got with hormones (still getting those too as times) are much milder, feel hot as well. I understand though that A-Fib can happen in some people with no symptoms at all and is only picked up by chance. The danger with A-Fib is that it makes it 5 times more likely to get a stroke which is why people are put on blood thinners. I start mine on Monday - dreading it but it has to be for life apparently in my case. Yuck xxx
