There are two bundle branches, right and left.
The left bundle branch divides into anterior and posterior fascicles, running along the septum. The right bundle branch is located in the right side of the interventricular septum.
The right bundle carries nerve impulses that cause contraction of the right ventricle (the lower chamber of the heart) and the left bundle carries nerve impulses that cause contraction of the left ventricle.
Nerve impulses come through the sinus node of the heart to the bundle of His and then move into the right and left bundle branches.
The bundle of His is the component of the conduction system located between the ventricles. It is responsible for transmitting electrical signals from the atrioventricular node to the Purkinje fibers in the ventricles.

The impulse starts in the right atria in the sinus node, then travels through the intratrial fibers for atrial contraction, then travels down to the the av node where it is delayed, then travels down through the bundle branches to the purkinjee fibers to the ventricular myocardium for contraction.

You can see the M pattern in ECG in place of ORS complex. In case of right bundle branch block, you see the M pattern in lead V one. In case of left bundle branch block, you see the M pattern in lead V six.
