left ax·is de·vi·a·tion

a mean electrical axis of the heart pointing to -30° or more negative. See: hexaxial reference system.

left axis deviation

Cardiology Any shift in the pattern of EKG leads; when seen with a counterclockwise loop abnormality in the frontal plane of a vectorcardiogram, LAD is typical of an ostium primum type atrioventricular canal defect.
