I've done so well for ages with my skipped beats worries. I have a Kardia monitor so I can catch any that happen and can send the ecg for review, which has helped enormously. I've started taking a magnesium supplement which also seems to have helped a lot. So all well until the other day when I randomly used my monitor and it came up with possible afib and a heartbeat of around 143, so of course I'm panicking. Thing is, I was aware of my heartbeat and it didn't feel anything like that speed. Mine is usually 80's or 90's, always has been really. Certainly didn't feel that high. The Kardia people are looking at the ecg to determine if the monitor was working properly... I'm hoping the battery might be going or something. Sorry for going on, I know you people will understand the worry
