I was 22 years old and also 7 monthes pregnant  when I was in my back yard cleaning up, bringing some tree limbs from the back to the front. When all of a sudden  felt like I could not catch my breath, So I ran inside and called 911, they came  and took me to the hospital found out that my heart rate was 200 so they  injected some stuff to restart my heart twice ...I didnt work so I stayed there for three days ad it finally went back down ... Has this ever happened to some one else???
