The number there were 12 lead ECG, each recording the heart's electrical activity from different angles, which is also related to anatomical areas that are different from the purpose of identifying acute coronary ischemia or lesions. 2 leads that look the same anatomical area in the heart said to be contiguous (see color coded chart).
• The inferior leads (leads II, III and aVF) look at electrical activity from the vantage point of the inferior wall (or diaphragmatic) left ventricle.
• The lateral leads (I, aVL, V5 and V6) look at electrical activity from the vantage point of the lateral wall of left ventricle. Due to the positive electrode for leads I and aVL are located in the left shoulder, leads I and aVL are sometimes referred to as the lateral leads. Because there is in the patient's chest, the positive electrodes for leads V5 and V6 are 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 left, which often dikelmpkkan together with the anterior leads.
• The anterior leads, V3 and V4 look at electrical activity from the vantage point of the anterior left ventricle.
• In addition, any two adjacent precordial leads are considered adjacent to each other. For example, even though V4 is an anterior lead and V5 is a lateral, two contiguous leads was due to close proximity to each other.
• Lead aVR offers no specific view of the left ventricle. Instead, this leads to see the inside wall of endocardium from the point of view on the right shoulder.
