Q waves
|
|
|
ST elevation in II, III, aVF and V1 + ST depression in precordial leads
|
RV infarct
|
|
|
R wave taller and wider in V1 and 2 than normal
|
Posterior wall infarct vs. RVH
|
|
|
ST depression without Q waves DDx
|
subendocardial infarct vs. cerebral hemorrhage
|
|
|
Q waves with persistent ST elevation and no reciprocal changes
|
ventricular aneurysm (versus pericarditis, where R wave will exhibit height variability, repolarization of atria)
|
|
|
How can you tell MAT vs. wandering pacemaker?
|
wandering pacemaker: HR <100
MAT: HR >100 |
|
|
How can you tell the difference between PAC and PVC?
|
PAC: QRS in the same direction and no compensatory pause (same R-R interval)
|
|
|
diffuse ST elevation <5mm +
reciprocal ST segment depression in aVR not aVL + PR depression (except elevated in aVR "knuckle sign") + ST concave up + ST elevation in II > III |
pericarditis
|
|
|
diffuse ST elevation + reciprocal changes + ST concave down + ST elevation in III > II
|
large MI
|
|
|
young male with diffuse ST elevation (+/- reciprocal changes in aVR but not aVL),
ST elevation in II > III, J point with notch (esp V4) and tall upright T waves |
early repolarization
|
|
|
wide QRS and tall, peaked, tented T waves
low amplitude or absent P waves ST segment usually downsloping |
hyperK
|
|
|
rSR' in V1 and V2
ST segment elevation in V1 and V2, typically downsloping |
Brugada syndrome
