Answer 3

V₁ - V₂ or III

Question 4

DDX for T-wave inversion

Answer 4

Inferior MI (in aVL only)

LVH strain

Increased ICP

PE

BBB

Ischemia (Wellens-B)

Question 5

Hyperacute T-wave is a sign of early ___

(However, also consider ___)

Answer 5

Sign of early ischemia (early STEMI)

Also consider vasospasm

Question 6

Biphasic T-wave DDX

If seen in ___ could be ___ occlusion

Answer 6

DDX: ischemia, HYPERkalemia

V₂ - V₃ could be LAD occlusion

Question 7

Flat T-wave can be ___ to ___ of deflection

DDX?

Answer 7

-1 mm to 1 mm of deflection

DDX: ischemia, HYPOkalemia

Question 8

Peaked T-waves are at least ___ in height

DDX?

__ - __ with upsloping ST-D is possible ___

Answer 8

10 mm

DDX: Hyperkalemia, hypermagnesemia, ischemia

V₁ - V₃ + upsloping ST-D is possible proximal LAD occlusion
