I m an 18 year old, 300 lbs. female and last friday I started having heart palpitations that lasted until this past thursday. They were constant but when I went to the doctor he said everything sounded normal. My blood pressure was 130/92 but he didn t mention anything about it. He said that it could be caffine or mitral valve prolapse. He told me I could see the heart doctor for an ultrasound to make sure everything looks normal. They stopped thursday and it s saturday now. I am having a little bit of discomfort in my back and I seem to be breathing fine except when go to bed and when I just wake up. I ve cut caffine out of my diet since the palps started. I still feel a bit weird but that could just be because I made myself worry over everything and my dad just had triple bypass surgery at 47 on his heart. Should I still see the heart doctor just to be safe or was it just anxiety or too much caffine?
