Infraction + Flashcards
Q waves v1 v2 v3 v4
?Reciprocal? II, III, AVF
Anterior infarction
Q wave I , AvL, V5, V6
Lateral Infarction
Q waves - II , III, AvF
Inferior infarct
Large R waves V1 V2 V3
St depression
Posterior Infarction
Circumflex branch of LCA perfuses
Lateral portion = L Ventricle
Anterior Descending Branch perfuses
Anterior portion = L Ventricle
Two main branches of L Coronary A. =
Circumflex
Anterior Descending
Right Coronary A. perfuses
Posterior portion = L Ventricle
Q wider than 1 square
Significant Q
Significant flat ST depression (Past Ischemia) =
Subendocardal Infarction
Flat/concave, elevated ST
Pericarditis
RBBB, ST elevation v1 v2 v3
Brugada’s syndrome
Large R wave in V1
Maybe: R axis dev
RVH
Deepest S v1 v2 \+ Tallest R V5 V6 = 35mm
LVH
Down-sloping ST = v5 v6
Cut-off s dip, then big gradual drop
Pressure overload, strain
Inverted Ts v1 - v6
Ischemia
1mm J point ST elevation in 2+ leads
Injury
Wide Q
Less so in AvR
Necrosis
ST elevation + wide deep Q =
ACUTE MI
QRS wide (3+) Wide S = I , v5, v6 Bunny ears= ~v2
RBBB
- Wide QRS (3+)
- Wide S = v1 v2
- Wide R = v5 v 6
- Bunny ears = ~V5
LBBB
*triad : hypotension, Clear lung, JVD + inferior infarct
- RBBB w/ CHB
- St elevation V4r
- inferior infarct (II, III, AVF)
R Ventricular Infarction
