So I've been obsessing over my heart rate just before bed.
After lying down for about 20mins my resting heart rate is averaging between 54-56bpm!!

I suffer with dizziness but am ok before bed it it's petrifying me! Why is it so low? I am in shape and run about 3k 3 times a week but wouldn't say I was in shape.

I had a 24 hour ecg last year and this wasn't mentioned... It's just really worrying me now and wondered if anyone else's heart rate is that low??
