Thanks for the compliment.
Can PACs cause AF -- yes, in the right person. At least for now, it sounds like you are not the right host. 1000s of PACs per day is a great stress test and it sounds like you haven't had AF yet.
The next issue becomes a mental health question and I think it is VERY important. One approach is to think -- "I have all these PACs and am at risk for AF and then spend hours worrying 'what if I develop AF'". This is not a fun way to live.
The other approach is to say "I have all these PACs and have never had AF. I guess there is a chance I might someday, but why don't I worry about that then...." The dali lama told me this once and promised me eternal happiness (I was his caddy).
