I was at my sister in laws sitting on a bar stool and all of the sudden i felt the need to cough. After I did I felt like I had a lump in my lower throat near my chest. Next thing I know my heart was pounding EXTREMELY hard, and shes a RN in the ER. She checked my pulse and it was 170!! We went to the hospital but by the time i got there it was 98, but my ekg was abnormal. Can anyone help?Oh by the way I am a 25 5 foot 3 white female that weighs 105.
