*ST depression > 1 mm in V1-V3 (concordance in ST deviation) (score 3)
*ST elevation > 5 mm in leads with a negative QRS complex (inappropriate discordance in ST deviation) (score 2). This criterium is sensitive, but not specific for ischemia in LBBB. It is however associated with a worse prognosis, when present in LBBB during ischemia.<cite>Wong</cite>
