I have been suffering from PVC's for a year and a half now. They started to occurr right after I had my thyroid taken out (cancer). I can totally related to what you felt. I will be driving, sitting at my desk at work or just around the house and all of a sudden I feel this big thud in my chest. The first time it happened it scared the life out of me. I was put on beta blocker medicine which dropped my heart rate into the 40's (my normal heart rate is high 50's, low 60's). Had to come off beta blocker because of this. Now I just deal with them as they happen here and there but the strong ones still scare the life out of me.
you see its gone one for what seems like 2 years. out of the blue i'll get one like that, maybe once every couple months.
Literally right now i feel fine. shopped at two stores after it and help my future mother in law move some stuff around in the garage for Christmas (heavy) and i had no issues
I have had exactly what you described. I don't get those very often and usually they are followed by a PAT episode (kind of like a pac switching gears or something).
I haven't felt faint during the episode either, but it does feel strange not feeling a pulse. Just like your body is numb. Hard to describe. The pause is probably not as long as you think. That is what I tell myself anyway.
