An incomplete right bundle branch block is an interruption in the heart's electrical conduction system. Incomplete means it has not completely failed.
i dont have a clue
A series of nerve bundles or groups enter down through the heart through the middle wall (septum)and split to come back upwards towards both the right and left chambers of the heart. If trauma, or more likely in injury due to small areas where the heart muscle has died, occurs there may be an interruption in the ability for nerve pulses to go past this point. This changes the regular (normal sinus) rhythm and speed of the heart beating into an irregular arrhythmia and is often associated with slowing of the heart rate.
Right bundle branch block happens less often from underlying heart disease.

It depends on what has caused the bundle branch block. Some healthy people will exhibit a bundle branch block (usually right sided) when their heart beats very fast. This is caused by a rate related delay in the bundle branch on that side, wherein the cells of the conduction system do not repolarize fast enough to propagate the electrical activity. If the block is caused by damage to the conduction tissue, then the bundle branch block will most likely be permanent.
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.
Bundle branch block belongs to a group of heart problems called intraventricular conduction defects (IVCD).
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.
Left bundle branch block is a delay or blockage in the electrical impulse conduction through the left bundle branch of the heart. Treatment for left bundle branch block depends on the underlying cause, such as heart disease or high blood pressure. It may include managing risk factors, such as controlling blood pressure, addressing heart disease, or considering a pacemaker in some cases.
Left bundle branch block affects the heart's electrical conduction system. When you have left bundle branch block, the left branch of this conducting system is partially or completely blocked. This causes the left ventricle to contract a little later than it should.
The two bundles initially are together at a junction called the bundle of His.
