Front Back
Acute Injury
Myocardium is dying due to lack of O2, this is the stage usually called a ""MI""
Axis
Direction of the vector of depolarization, normal is 0 to 90o
Bundle Branch Block
Can determine which bundle branch is blocked by using lead V1. A left BBB will be a negative deflection .12 secs or greater. A Right BBB will be a positive deflection .11 secs or greater. If pt has a LBBB, you can not diagnose MI from the 12 lead EKG.
Early Repolariztion
Can mimic ST elevation, this is commonly seen in healthly black men as a normal condition
Infarct Location
Leads II, III, aVF = inferior wall MI or DMI Leads I, aVL, V6 = Lateral wall MI Leads V1, V2 = Septum Leads V3 , V4 = Anterior wall Leads V5 , V6 = Anterior lateral wall
Ischemia
Heart is starved for O2 but no permanent injury
Pericarditis
Generalized elevation of the ST segments with an upward concavity in many leads including all three standard leads
Subendocardial Infarction
The subendocardium is especially vulnerable to infarct because being close to the ventricular cavity, it is subject to high pressure & is first effected when coronary perfusion is inhibited. Cannot be easily recognized from EKG.
Wolf-Parkinson-White (WPW)
Characterized by the Delta wave & very small ' PR ' interval & wide ' QRS '.
