==Conduction delay==
[[Image:geleidingssysteem.jpg|thumb| If the conduction system is dysfunctional, the QRS widens beyond 0.12 seconds.]]
If the QRS complex is wider than 0.12 seconds this is mostly caused by a delay in the conduction tissue of one of the bundle branches:

== LBBB vs RBBB ==
[[Image:LBTB_RBTB_en.png|thumb| A bundle branch block causes a delay in the depolarization of the right (RBBB) or left (LBBB) ventricle. In RBBB the QRS complex shows a second peak or R' in V1.]]
Check V1 when QRS > 0.12 sec.
