What is the cardiac axis?

The average direction of spread of the ventricular depolarisation (usually downward and to the left)

32

What is left axis deviation?

This occurs when overall direction of ventricular depolarisation is upwards and to the left (less than 30 degrees). May occur as a result of conduction block of the anterior branch of the left bundle, inferior MI or left ventricular hypertrophy

33

What is right axis deviation?

When overall direction of ventricular depolarisation is downwards and to the right (more than 90 degrees). Associated with right ventricular hypertrophy
