Last night I couldn’t sleep. After fitfully lying there for a few hours I suddenly had a very fast pounding heart rate of about 130. I couldn’t get it to stop for about 30 mins. Which made me panic and then I felt like I couldn’t breathe - but I think that was anxiety. It eventually stopped. But I still couldn’t sleep, kept jolting awake.
I’m on HRT and not had this before - am 49 years old. Any ideas?
