I've been having fast heartbeat for some time now and yes, I usually get it during my sleep. I'll wake up with my heart racing so fast that I sometimes cannot even count it. It always gets worse when I'm on antibiotics. I never knew if it was my thyroid, because I have Hashimotos or if it was sleep apnea or just Lyme. It's very scary when it happens and I usually have to take something to calm it down.
Did this just start for you when you took the antibiotics?
