When the bundle branches are functioning normally, the right and left ventricles contract nearly simultaneously.

The right and left bundle branches send the electrical impulse to the right and left ventricle, respectively. From the His bundle, the electrical impulse enters the two “bundle branches” (the right and the left). Leaving the AV node, the electrical impulse penetrates into the ventricles via the His bundle. To summarize, the heart’s electrical impulse originates in the in the sinus node in the upper right atrium, then spreads across both atria, then travels through the AV node. The bundle branches are an important part of the cardiac electrical system, the system that coordinates muscular contraction to assure that the heart works efficiently as a pump.įigure 1 – The Normal Electrical System: AVN = AV node, His = His bundle, RBB = right bundle branch, LBB = left bundle branch, RA = right atrium, RV = right ventricle, LA = left atrium, LV = left ventricle What are the bundle branches, and what do they do? In this article, we will review bundle branch block, its significance, and its treatment. Sometimes BBB itself needs to be treated sometimes it indicates significant underlying cardiac disease that needs to be treated and sometimes it has so little significance that no treatment is necessary at all. Fogoros, M.D., Guide, November 26, 2003, that I reprint here:īundle branch block (BBB) is a relatively frequent finding on the electrocardiogram (ECG).

Can LVH be reversed?Ī number of studies point to improved outcomes for people who are treated for LVH. If LVH is caused by a heart valve problem, surgery may be needed to repair or replace the valve. Depending on the type of damage that has occurred, treatment measures may include medications and heart-healthy lifestyle changes to help reduce the pressure in the heart. LVH can often be corrected by treating the underlying problem causing the heart to work too hard. MRI imaging of the heart can also diagnose LVH. However, a routine electrocardiogram or echocardiogram can usually diagnose LVH, even before symptoms become noticeable. How's LVH diagnosed?īecause LVH can develop silently over several years without symptoms, it can be difficult to diagnose. It's important to treat the causes of LVH early because it can lead to severe problems such as heart failure, sudden cardiac arrest and ischemic stroke. Heart valve problems like stenosis or regurgitation.LVH usually happens as a result of other heart problems such as: How's Left Ventricular Hypertrophy related to other heart problems? If you are experiencing any of these symptoms, talk to your health care provider right away so that the problem can be identified and treated. As the condition worsens, symptoms may develop, such as: LVH may be present for many years without any noticeable symptoms. These thickened walls can cause the left ventricle to weaken, stiffen and lose elasticity, which may prevent healthy blood flow. In response to this pressure overload, the inner walls of the heart may respond by getting thicker. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle. Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently.
