Looking at the precordial leads, the R wave usually progresses from showing an rS-type complex in V 1 with an increasing R and a decreasing S wave when moving toward the left side. There is usually a qR-type of complex in V 5 and V 6, with the R-wave amplitude usually taller in V 5 than in V 6 .

The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. The hexaxial reference system, better known as the Cabrera system, is a convention to present the extremity leads of the 12 lead electrocardiogram, [1] that provides an illustrative logical sequence that helps interpretation of the ECG, especially to determine the heart's ...

Inverted T wave is considered abnormal if inversion is deeper than 1.0 mm. Inverted T waves found in leads other than the V1 to V4 leads is associated with increased cardiac deaths. Inverted T waves associated with cardiac signs and symptoms ( chest pain and cardiac murmur ) are highly suggestive of myocardial ischaemia . [ 4 ]
12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1–V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. When there is a blockage of the coronary artery , there will be lack of oxygen supply to all three layers of cardiac muscle (transmural ischemia).
