Check V1 for QRS > 0,12 sec.
Check V1 when QRS > 0,12 sec.
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.  
When the last activity is above the baseline, it's a RBBB.
When the last activity is above the baseline, it's a RBBB.
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.
