Sometimes there is no known cause. Left bundle branch blocks In left bundle branch block LBBB the left ventricle is not directly activated by impulses travelling through the left bundle branch. Acls Certification Institute Google Cardiac Nursing Paramedic Acls W i LL iam If the QRS looks like M in V1 and W in V6 it is RBBB. Right vs left bundle branch block ecg . W pattern in V1-V2 and M pattern in V3-V6 is L eft bundle block. In normal cardiac conduction impulses travel equally down the left and right bundles with the septum activated from left to right and the formation of small Q waves in lateral leads In LBBB conduction delay means that impulses travel first via the right bundle branch to the RV and then to the LV via the septum. Again false false false. In the general population an apparently similar phenomenon but with different pathophysiology and potential consequences crista supraventricularis pattern CSP defined as QRS 100 ms S wave.
