I need a little reassurance here, not sure if people have been in the same shoes as me. I am 18 years old with no family history of heart issues and no risk factors for heart issues. I have gotten both an EKG and a heart ultrasound, and both came back normal. I still get worried about my heart due to the fact that my heartbeat feels fast when doing any sort of thing, and it feels like it switches from a strong heartbeat to a soft one. I consistently have been getting palpitations and have been checking my pulse. I have constant awareness of my heartbeat and it’s VERY frustrating because of my history and the tests I have gotten done, you’d think I wouldn’t worry about my heart.
