Question | Answer |
---|---|
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 |
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 | Characterized by the Delta wave & very small ' PR ' interval & wide ' QRS '. |
AAA | Aortic Abdominal Aneurysm |
ACE | Angiotensin Converting Enzyme |
