Flashcards
12 lead STEMI mimics
Cards in this deck (5)
- 1Left bundle branch block, diagnostic criteriaQRS > 0.12s
Dominant S wave in V1
Broad monophasic R wave in lateral leads
Absence of Q waves in lateral leads
Prolonged R wave peak time >.06s in V5-6
Bonus: ST segments and T waves always go in the opposite direction to the main vector of the QRS complex - 2Right bundle branch block, diagnostic criteriaBroad QRS
RSR' pattern in V1-3 (M-shaped QRS)
Wide, slurred S wave in lateral leads
Bonus: chest leads largely unaffected - 3Pericarditis, diagnostic criteriaWidespread concave ST elevation in PR depression through most of limb leads and precordial leads (V2-6)
Reciprocal ST depression and PR elevation in aVR
Sinus tachy common - 4Benign early repolarisation, diagnostic featuresWidespread concave ST elevation, most prominent in V2-5
Notching or slurring of the J point
Prominent, slightly asymmetrical T waves that are concordant with the QRS complex
Degree of ST elevation is modest in comparison to T wave amplitude (<25% of T wave height in V6)
No reciprocal ST depression to suggest STEMI (except in aVR) - 5Left ventricular hypertrophy, diagnostic criteriaS wave depth in V1 + R wave height in V5-6 is >35mm, plus:
Increased R wave peak time >.05s in V5or 6
ST segment depression and T wave inversion in the left sided leads
