A member asked:

I had an echo stress(neg) for shoulder pain, a holter monitor (showed pacs). extra beats especially when walking. how does dr.know it's benign?

A doctor has provided 1 answer

Very common: PAC's are very common and occur in almost everyone. They are considered benign if they are random occurances, cause no symptoms, do not occur in long strings, and do not occur at a dangerous part of the hearts electrical cycle.
