Left Main Coronary Artery (LMCA)
41
Coronary) Right coronary artery (RCA) supplies: Right Coronary arteries' 2 major branches:
= part R-atrium & ventricle, upper part conduction system = posterior descending artery & marginal artery
42
Congitual: Reciprocal changes: Spodicks sign:
= same view leads = mirrored effect in oppisute/corresponding leads for sure MI = pericarditis PR slopes down aka STEMI imposter
43
Leads 2, 3, aVF reciprocal leads
leads 1, aVL, V1-6
44
Leads 1, aVL, V1-6 reciprocal leads
2, 3, aVF reciprocal leads
45
Wellen’s wave type A:
Biphasic T waves in V2 or V3, min STE <1mm (V2 usually biggest shower Highly specific for for a critical blockage of the LAD
46
Wellen’s wave type B:
DEEP inverted T waves V2 or V3,
47
De Winter’s T Waves:
V2 V3 most commonly but can happen any lead ST depression at the J-point & upsloping ST-segments w/ tall, symmetrical T- waves in the precordial leads (LMCA or LAD occlusion) “Hyper T w/ STD”
48
Spodicks sign:
sloping down P wave into QRS (evidence of pericarditis)
49
3 Is of cardiac) Ischemia: “Infarct” Injury: Infarction:
= Ischemia: ST depres/, Hyperacute T waves>5chest avf >10 precordial = “Infarct” Injury: ST elevation 50%, = Infarction: old MI; >25% Q or QRS >1SB

RPM: LAC:
RPM: Posterior & Marginal LAC: anterior descending circumflex
51
LBBB Definer Turn criteria
Down deflection before J point "turning left"
52
Mirror Criteria
V1&2 leads (v2 most sensitive w/ R): ST depression w/ big R wave (accompany 15-20% inferior or lateral STEMI)
