Cardiac axis Cardiac axis describes the overall direction of electrical spread within the heart. In a healthy individual the axis should spread from 11 o’clock to 5 o’clock. To determine the cardiac axis you need to look at leads I,II and III. Normal cardiac axis In normal cardiac axis:     Lead II has the most positive deflection compared to Leads I and III . Right axis deviation In right axis deviation:      Lead III has the most positive deflection and Lead I should be negative      This is commonly seen in individuals with right ventricular hypertrophy Left axis deviation In left axis deviation:      Lead I has the most positive deflection      Leads II and III are negative      Left axis deviation is seen in individuals with heart conduction defects
