Sgarbossa Criteria (> 3 points才像STEMI)
[5-points] > 1 mm STE Concordance (any leads除了V1~3)
[3-points] > 1 mm STD Concordance (V1~3) (因為正常的LBBB其V1~3是STE)
[2-points] > 5 mm STE DISCONCORDANCE
Modified Sgarbossa Criteria (Sen. 59 --> 85%, Spec. 99 --> 96%)
把2-point的criteria改成: STE DISCONCORDANCE in lead V1~4且同時符合以下criteria:
(a) ST / S ratio > 0.2
(b) > 2 mm STE
