just recently i was laying in bed and all of a sudden i got a feeling in my chest that scared me. Im a 26 y/o male with a history of pvc's on verapamil 240mg every night. My heart just started pounding out of my chest very fast, like 6-7 times in a row in 3 seconds, got scared and jerked up and it stoped. This has happened before, the day before my holter monitor, and it did not check the next day. Was this a "run" of pvc's? or was this a quick burst of hard heart beats? The last time it happened, i was taking my pulse and i could feel it in my wrist, but i was too shocked to focus on taking it this time. Anyone?
