The electrical axis of the heart (heart axis) Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction.
There are a number of ways (of varying accuracy) via which to calculate a cardiac axis using an ECG and the hexaxial reference system, pictured below. Method 1. The Quickest Way. It’s as simple as following this table: Method 2. The Nearest 30° Identify the most isoelectric lead on the ECG and then on the hexaxial reference diagram

Cardiologists analyze the heart using cardiac axes. These axes are also used in cardiac CT/MR and must be reconstructed in order to assess the heart properly. Axial slices, such as those imaged on the left, are useful for a global assessment of the morphology of the heart and its relation to the pericardium.
