Is regular sinus rhythm, left axis deviation, low voltage complexes and intraventricular conduction defect a normal or abnormal ecg result?

Abnormal: Could be an abnormal conduction pathway or result of another disease process. The result could also simply be a computer reading of a test performed improperly. Hard to know without more information. There is a physician in charge of the interpretation (or the ordering physician or primary care doctor) that can provide more informed advice.
