Lbbb with inferior mi
WebIn LBBB, V1-V3 always have a predominant S-wave (QRS is predominantly negative) and therefore ST depression (STD) in V1-V3 is always concordant; ≥ 1 mm of STD in just one of these leads is diagnostic of STEMI (posterior STEMI, in fact). Finally, where Sgarbossa found 5 mm of discordant STE to be fairly specific for MI,* we found that an ST ... WebOmar Salem’s Post Omar Salem Internist 4y
