Hey guys so here for the past couple of months I've had weird nervous feelings in my chest. Every now and then my chest will have a fluttering feeling that's pretty intense. This happens maybe every few weeks or so if that. My doctors have done numerous tests on me but everything has been normal so far. EKGS and blood tests. I had an ultrasound of my heart back in February and things were normal but I wasn't having these feelings like I am now. I don't know if it's just my anxiety or if it really is afib. My heart rate has been slower than normal, around 59-65 when I'm laying down and around 70-90 when sitting or standing up. Maybe it's just my hypochondria but please give me insight! Thanks so much.
