When the last QRS in V1 is below the baseline (moving away from V1), a LBBB is the most likely diagnosis. | When the last QRS in V1 is below the baseline (moving away from V1), a LBBB is the most likely diagnosis. | ||

If the QRS > 0.12 sec. but the morphological criteria of LBBB or RBBB do not apply, it is called 'interventriculair conduction delay', a general term. | If the QRS > 0.12 sec. but the morphological criteria of LBBB or RBBB do not apply, it is called 'interventriculair conduction delay', a general term. | ||
