VE = ventricular ectopics (beats originating from the hearts main chambers)
SVE = supraventricular ectopics (beats originating from upper chambers, except sinus node)
Hope this helps.
VE also know as pvcs premature ventricular contractions and SVE also known as pacs premature atrial contractions. Almost everyone with have some of one or the other or both on a 24 hour monitor
