Fainting spells and cardiologists

Last week after a terrific medium long run with a friend, I went directly to a running club meeting and passed out cold when I stood up afterwards, hitting my head pretty hard on a concrete floor. Many friends encouraged me to get a physical so I relented. In retrospect, I knew where I went wrong that day and my primary care physician agreed that it was probably due to low blood pressure, poor fueling and hydration, and lack of cool down. However, he recommended an echocardiogram stress test thingy because, "afterall, you ARE 46 and deserve one."

I went to the cardiologist and sat nervously in the waiting room with 6 people who must've been in their 80's. I am too young and healthy to be here. My name was called and the test was performed. I was able to see my heart pumping on the ultrasound machine so that was cool. I lasted almost 16 minutes with an 18% grade. Results: My heart is fine. I have low blood pressure that gets even lower with exercise instead of raising like many people's. Poor fueling and hydration exacerbates this so I really need to be more careful with fueling, hydration, and cool down.

So if you see me passed out cold somewhere, please elevate my feet.
