My name is jamie. female 17 years old. ive been struggling with my heart palpitations since i was 13 ive had a heart monitor blood work and all types of other stuff done. they said i had a defformed heart valve but it " meraculously healed itself " when i turned 17. usually i dont mind the palpitations i just bare down and take it but last night my chest heart and so did my uper back by my lungs. i felt like i couldnt breath deep enough and i went back and forth from hot to cold... today my chest still hurts but not as muvh and my breathing is the same... i get these weird heart beats where it will beat once really hard and i feel like im getting the life sucked out of me... what can i do... whats wrong with me?
