My heart feels a lot faster when lying down anyone else had this?

Hi there my heart feels as if it is beating a lot faster when im lying down but when I get up and check it on the clock in the kitchen it was 82. But when I go and lie down again it feels as if it beating a lot faster has anyone else had this? I feel like im going mad rushing up and down all the time

Yea I get this especially when I'm on my back, think it's just easier to feel your heart when you're lying down? Don't think it's anything to worry about especially as it was only 82 when you took it, that's well within normality. :) xx
