Hi I just turned 20 and I've been having these strange heartbeats that only happen when I'm laying down/relaxed. And these are constant I mean back to back to back and won't stop unless I cough or get up. I've had numerous ekgs and all comes back normal that I have a structurally normal heart and I'm fine. I never get any symptoms so I guess that's good but it still concerns me. I can't find any correlation with this at all. I've tried not drinking any caffeine, eating healthy and all of that but nothing fixes it. I've even tried beta blockers but that doesn't help at all considering I only get them when I'm relaxed and my heart rate is normal/resting. So my heart rate being slower because of beta blockers well yeah just doesn't do anything. I just want to know if this is benign or ok. Like I said I have no symptoms but there's are very constant. Here's a picture of my rhythm when I'm relaxed.. https://imgur.com/a/FfaSviD I've been searching and can't find this heart rhythm anywhere so any help would be greatly appreciated!
