	**[[ST Elevation]] most prominent in ~~lat precord~~ leads (V4-6) ~~but no~~ reciprocal ~~changs~~		**[[ST Elevation]] most prominent in lateral precordial leads (V4-6)
			***Lack of reciprocal changes helps to differentiate from STEMI
	**T waves usually broad, tall (>5mm) & upright		**T waves usually broad, tall (>5mm) & upright
	**Limb leads may also have ST elevation, rarely >2 mm		**Limb leads may also have ST elevation, rarely >2 mm
