Hexaxial reference system
Hexaxial Reference System
The Hexaxial Reference System (pronunciation: /hɛkˈsæksɪəl ˈrɛfərəns ˈsɪstəm/) is a method used in Electrocardiography to interpret the magnitude and direction of electrical forces within the heart. This system is also known as the Cabrera system or the circular system.
Etymology
The term "Hexaxial" is derived from the Greek words "hex" meaning six and "axia" meaning axis. This refers to the six main axes or leads in the system. The term "Reference System" indicates that it is a standard or guide used for comparison or evaluation.
Description
The Hexaxial Reference System is a two-dimensional representation of the three-dimensional electrical activity within the heart. It is used to determine the heart's electrical axis, which can provide important information about heart health and function. The system uses six limb leads (I, II, III, aVR, aVL, and aVF) and six precordial leads (V1-V6) to create a comprehensive view of the heart's electrical activity.
