I have pacs a lot after eating, 2 diff cardios say they're benign but they're running my life. why do i have days with none and then sometimes they happen all day, sometimes i'll have 3-4 in 20 secs, scares me so bad but cardio said it's ok?

PACS: You saw a cardiologist, a heart expert who probably ran several tests to support his conclusion that things are ok from his point of view. Is it possible you have dumping syndrome a flushing reaction after eating too much or heavy foods? Or is possible that all the tests that can be done to assure who will not remove the anxiety which can be your issue? Ask your primary care doctor.
