   Left-axis deviation is when the QRS axis is between -30° and -90º. Moderate left-axis deviation is between -30° and -45°. Marked left-axis deviation is from -45° to -90° and is often associated with left anterior fascicular block 1. The situations in which left-axis deviation may be seen are as follows:
