EKG Machines: Introduction to Clinical Lead Groups
A QRS Brand Review of EKG Machines 


It seems were not yet done in discussing with the technicalities of defining the process of electrocardiography is. For this article, we will expound the meaning of Clinical Led Groups in electrocardiogram.

There are twelve leads in total, each recording the electrical activity of the heart from a different perspective, which also correlate to different anatomical areas of the heart for the purpose of identifying acute coronary ischemia or injury. Two leads that look at the same anatomical area of the heart are said to be contiguous.

• The inferior leads (leads II, III and aVF) look at electrical activity from the vantage point of the inferior (or diaphragmatic) surface.
• The lateral leads (I, aVL, V5 and V6) look at the electrical activity from the vantage point of the lateral wall of left ventricle. The positive electrode for leads I and aVL should be located distally on the left arm and because of which, leads I and aVL are sometimes referred to as the high lateral leads. Because the positive electrodes for leads V5 and V6 are on the patient's chest, they are sometimes referred to as the low lateral leads.
• The septal leads, V1 and V2 look at electrical activity from the vantage point of the septal wall of the ventricles.
• The anterior leads, V3 and V4 look at electrical activity from the vantage point of the anterior surface of the heart.
• In addition, any two precordial leads that are next to one another are considered to be contiguous. For example, even though V4 is an anterior lead and V5 is a lateral lead, they are contiguous because they are next to one another.
• Lead aVR offers no specific view of the left ventricle. Rather, it views the inside of the endocardial wall to the surface of the right atrium, from its perspective on the right shoulder.
