A new or presumably new left bundle branch block along with ischemic symptoms has traditionally been considered an electrocardiographic equivalent of ST-segment elevation myocardial infarction, which should be brought to emergent reperfusion. However, several criteria have been proposed for its definition, but none has reached out an optimal diagnostic yield. Below we detail these criteria, their main problems and the advantages they have shown.
