| Early Repolarization |
1. Normal varient most commonly seen in young males.
2. The early repolariztion (relaxation) of some myocardial fibers may deviate the ST upwards in a concave pattern, especially when R waves high with tall peaked T waves.
3. The J point is frequently elevated (where the QRS joins the concave ST elevation).

Differentiation from Pericarditis:
|
A ST/T ratio in V6 of 0.25 will allow good separation of the two entities |
|
|
|
Differentiation from MI:
|
ST segment elevation is typically less pronounced (equal to or less than 0.05mV) and the ventricular surface area is greater (more leads involved) |
