The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.

Nov 17, 2024 · For a deeper understanding of axis determination, including a detailed explanation of the hexaxial reference system, check out this excellent series of articles from EMS 12-lead.

Mar 17, 2025 · If you want to know the exact location of the cardiac axis (for example: "The axis is located at exactly 63º"), you should measure the QRS in leads I and III, translate the measurements …

The hexaxial reference system is a diagrammatic tool in electrocardiography (ECG) that represents the heart's electrical activity in the frontal plane through the six standard limb leads—I, II, III, aVR, aVL, …

In the hexaxial reference system, each lead is assigned an electrical axis depending on its orientation in the body. X-axis is formed by lead I which has a horizontal orientation with positivity towards left.

Next, please note we always show the LIMB LEADs at their POSITIVE pole and show this on the hexaxial diagram.

The hexaxial reference system is diagram based on the first six leads of the 12 lead ECG. It is used to help determine the heart's electrical axis in the frontal plane.

What is the Hexaxial reference system? The hexaxial reference system is a convention to present the extremity leads of the 12 lead electrocardiogram, that ...

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 hexaxial reference system is diagram based on the first six leads of the 12 lead ECG. It is used to help determine the heart's electrical axis in the frontal plane.
