Clinical Significance of Left Axis Deviation

Abstract

Left axis deviation is always a matter of concern since it is often seen without other apparent electrocardiographic abnormalities and the physician must decide whether or not its presence is significant to the patient. The results of an army study of 195 men with left axis deviation compared with a normal control group over a period of 22 months indicated that left axis deviation is highly suspect of associated atherosclerosis. Experience has shown a higher operative risk for the patient with left axis deviation in combination with anterolateral peri-infarction block.
