A ventricular ectopic beat is an extra heartbeat originating in the lower chamber of the heart. This beat, also called a premature ventricular contraction (PVC), occurs before the beat triggered by the heart's normal function.
Ventricular ectopic beats are common and do not indicate a problem in people without heart disease. However, if a person has aortic stenosis, heart failure, or a previous heart attack, VEBs may be followed by ventricular tachycardia and fibrillation, which can lead to sudden death. Worst case scenario.
An EKG or ECG is not a very good soruce for diagnosing a heart condtion other than rhythm problems. EKG information requires confirmation with other clinical evidence and tests. Usually, an echocardiogram is a followup test, and if there is heart cell damage there will be hypokinesis (heart wall movement impairment) and the heart will pump less than normal.
