QDM, you realy are a gem to this forum! My ECG, taken recenty, also indicated (at least the machine was offeirng it as an option) that my left chamber is slightly enlarged. It was the first time anyone mentioned it, which got me worried. I'm also rather active as regards sports training. I tend to work out 4-5 times per week, mostly strenght training.
Anyway, just thought I'd let you know that some of us appreciate it that you take the time to reply to our questions. It helps relieve ones anxiety.
