1 The term "incomplete" for IRBBB and ILBBB implies conduction is delayed, but not completely blocked. back
2 QRS is positive in leads V1 and V2, similar to RBBB. back
3 QRS is negative in leads V1 and V2, similar to LBBB. back
4 Unlike WPW, QRS complex has normal morphology in LGL. Activation of the ventricles occurs entirely through the bundle of His and the bundle branches. back
