Jessica, I'm just wondering if they did more than listen you your heart. Did they do any other tests on it. And they cleared you for this? Sometimes this stuff means that your heart can't "relax" between beats. Which means it can't fully pump the blood by getting a full contraction. Just imagine your muscles having to work against something in a state of constant contraction...you can see that you would never be working with full force. They didn't say anything about that? I had "tachycardia" before I went in the Air Force so they were worred about things like that. But my regular doctor cleared me saying it was "just fast and always had been". Truthfully, I don't think he did enought to determine if there was a realy problem, but I don't know. Anyway, it's since gone away and as far as I know has never come back.
At the time...I used buttermilk to slow it down for my re-examine by the MEPS. It worked wonders
