Damage to the left bundle branch would prevent the left ventricle from contracting as normal. The left ventricle pumps blood to the rest of the body minus the lungs, i.e. the systemic circuit.

How would damage to left bundle affect blood flow in systemic circulation?

Left ventricle wouldn't be able to contract so that oxygenated blood could get to the body tissues.


What causes right bundle branch block?

Right bundle branch block happens less often from underlying heart disease.


What is a bundle branch composed of?

Purkinje fibers.


Is right bundle branch block reversible?

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.


What group of heart problems does the bundle branch block belong to?

Bundle branch block belongs to a group of heart problems called intraventricular conduction defects (IVCD).


What does right bundle branch block mean?

An incomplete right bundle branch block is an interruption in the heart's electrical conduction system. Incomplete means it has not completely failed.


If a myocardial infarct destroyed a portion of the right or left bundle branches what potential change might you see in the ECG?

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.


Location of the Left and right bundle branches?

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.


What is left branch bundle block and what is the treatment for it?

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.


What is the twisted bundle of hay called used to aid a horses circulation?

If a myocardial infarction damaged the left bundle branch how would this affect the spread of the action potential?

Ventricular depolarization takes longer because impulses in the left ventricle must travel from cell to cell rather than traveling down the left bundle branch and Purkinje fibers. (This will lead to a longer QRS complex on an ECG)


Are incomplete right bundle branch blocks dangerous?

Yes
