Right axis deviation occurs when the QRS axis is shifted between 90 and 180 degrees. A number of things can result in right axis deviation which include lung disease, right sided heart strain, right bundle branch block, and right ventricular hypertrophy.
What causes a right axis deviation?
The pathophysiology depends on the specific cause of right axis deviation. Most causes can be attributed to one of four main mechanisms. These include right ventricular hypertrophy, reduced muscle mass of left ventricle, altered conduction pathways and change in the position of the heart in the chest.
What does a right axis deviation mean on an EKG?
Right Axis Deviation = QRS axis greater than +90° Normal Axis = QRS axis between -30° and +90° Left Axis Deviation = QRS axis less than -30° Extreme Axis Deviation = QRS axis between -90° and 180° (AKA “Northwest Axis”)
