I have had 2 PEs, with different symptoms each time. I was on coumadin for a year after my 1st one. Now, after 2, I am on for life.
First PE:
I almost passed that morning. Everything went black while I was in line at a bagel shop. The staff tried to call an ambulance. I didn't let them.
My resting heartrate was around 125 beats per minute.
I had trouble breathing after walking across a room.
I slept most of the day, but if I got out of bed to walk to the bathroom, my heart would beat so fast that I would have trouble falling back to sleep.
I had no pain.
My PE was massive and bi-lateral.
Second PE (4 years later):
I had heaviness/pressure in my chest on the L side.
I would wake up in the middle of the night with my heart pounding.
I couldn't sleep on my left side w/out my heart pounding too hard.
I sometimes felt the presence of my heart, like a hard heavy baseball in my chest.
I could breathe just fine and my heart rate was not elevated.
The second PE was small and only in my left lung.
