Cool. That sounds like a pretty classic 2nd Degree Type 1 Atrioventricular Block (also know as a Wenckebach block).
If the area of infarct impacts a part of the heart responsible for electrical conduction, stuff like that can absolutely happen, but it's not especially common.
Apparently I'm weird because I wanted to watch the angio. They kept telling me that they "didn't need my help" :)
I was saying "how often do you get to see your insides?"
