(Created page with "'''Bundle branch blocks''' are conduction blocks in the left or right bundle branches. The Bundle of His divides into the left bundle branch and right bundle branch. Blocks in these conducting pathways cause the depolarisation of part of the ventricle to occur later than the rest, resulting in a wide QRS complex.
