A little bit ago, while running, I pretty much fainted. I lost my balance, couldn't see straight (everything was blurry) or hear but I never blacked out.

After seeing a cardiologist, they recommended an MRI. I just found out about the MRI results and apparently, I have a large left ventrical.

I was wondering if anyone had any idea what the hell this means? Are there any restrictions? My cardiologist is out of town for another week. I went for a 5 mile run today and felt fine. This fainting episode has only happened once although I have noticed that there have been times I feel the same initial feelings coming on. I felt it coming on at the hospital and while strapped to a heart rate monitor, my HR dipped into the mid to high 30's during that brief period.

Also, I don't know if it makes any difference, but my resting heart rate is 42.
