My aortic valve regurgitation has progressed from mild to moderate. I have noticed, especially when going to bed, that my heartbeat has become much more forceful. To the point of being annoying. I know this sounds funny, but it is quite unconfortable. I try to find positions that reduce this feeling. Nothing seems to work. Have you ever heard of this before? Sould I be concerned. Thank you very much. I am a 48 y/o female.
