Hi I have suffered from palpitations for years and am taking a low dose of atenalol. For the past couple of days I have been feeling dizzy constantly, every time I move even my eyes, I have also been breathless, this also happened a few months ago and lasted for a couple of days. Tonight whilst I was having a relaxing bath I had a huge palpitation which was quite scary, I am stil dizzy and when I et the dizzy Feeling I get a flutter like the start of a palpitation, and feel breathless.
