Good luck with the echocardiogram. As long as they warm the gel before they slop it onto your chest, you should find the whole thing lacks any discomfort. I say that because I had an breast ultrasound once and they didn't warm the gel - brrrr! They may be able to show you images of your heart as they do the test, which is kind of wierd seeing into your body in black and white. Let us know what happened when you get back.
