That's serious heartburn, Jackie.
GROAN! It was, actually, but it didn't hurt a bit.
The doc threaded this device into my heart, where it located and closed off (with laser, I think) the places where the electrical impulses were slipping through where they shouldn't oughta. And only a tiny incision, just big enough for the device. Isn't that amazing? They can go into--right inside!--your heart and do stuff, and not only do you live, you can barely tell anything's happened!
