*ST elevation is localized

T, STD	Ischemia
STE	Infarct
R	Viable Myocardium left
Q	Past MI/Scare

Signs:

Hyperacute T (> 2/3 of RR)

ST Elevation : ST (J) vs TP baseline (after T wave)
Pathological Q wave : > 1 mm (40 ms), > 25-30% of R wave, 2+ regional
TWI : -0.1 to -0.5 mV in non-R-sided leads (not aVR, III, V1)
may present as new LBBB: LBBB - Left Bundle Branch Blockage ECG

Evolution:

Hyper-acute (1h)

Hyperacute T (> 2/3 of RR) First few (10-15) min: can see T waves ****being elevated , sharp
