Our website services, content, and products are for informational purposes only. The left bundle branch is subdivided into the following two fascicles: (1)the anterior (anterosuperior) fascicle, whichdelivers the electrical impulse to the anterior wall of the left ventricle; (2)the posterior (posteroinferior) fascicle, whichdelivers the electrical impulse to the posterior and inferiorwalls of the left ventricle. P mitrale (bifid P waves) and left atrial enlargement are common P wave abnormalities. This is due to the fact that the posterior fascicle is larger and it has greater arterial supply.
