I was wondering: I seem to be in a prolonged to non-stop period of "flutter" when not in Afib. Not sure what it is, but my heart seems to "role" and spasm. Not uncomfortable but annoying. Can anyone tell me what this is? I often wonder is it Palpatations? I know what an attack of Afib feels like, my heart jumps from 54 bpm to 120 bpm and stays there for some time. Any ideas? Thanks.
