Thanks, LT. My dad had a couple of them years ago, and my uncle just had one put in recently, so I'm a little bit familiar with the procedure anyway, enough that it's not as scary as it would be if I didn't already know people who've had them put in. It also helps that the cardiologist was so patient with my questions and concerns today, I feel comfortable that I can call and ask to talk to him if I have more questions as the time gets closer.
