Determining the Axis (Vector) Axis Deviation is the description given to a shift in the mean flow of electrical depolarization of the heart. The normal depolarizing wave front is from right to left in a downward fashion: from right shoulder to left foot. One way to determine axis is to use only leads I and aVF. The normal axis of the heart should be represented as a positive deflection in lead I and a positive deflection in lead aVF. Lead I records the electrical wave front from
