Intermittent Left Bundle Branch Block
There are 2 main branches of the heart's electrical system within the ventricles, the right bundle branch and the left bundle branch. Additionally, the left bundle branch has two sub-branches, the antero-superior fascicle and the posteroinferior fascicle. When one or more branches are disrupted, the resultant electrical abnormalities can be ...Read more
The cause important: The right bundle is relatively easy to damage, so relatively small injuries can create it. The left bundles (two of them, one easy to injure, one hard to damage) require more damage to interfere with their function, so they are associated with "worse" heart disease with the prognosis inherent in your question. Cause is important, so need to talk to your doctors to sort those out. ...Read moreSee 1 more doctor answer
The location: Obviously the location of the electrical block in the conduction of electric impulses from the atrium to the ventricles is different. The electrical signals travel to the two ventricles through the left and the right bundle, the left then bifurcates to two fascicles itself. In my experience, the non-pathologic presence of right bundle branch block is more common. ...Read moreSee 1 more doctor answer
What is the difference between complete right bundle branch block and incomplete right bundle branch block?
Abnormal conduction: The signal to beat is distributed to through the heart by a specialized electrical system. The right bundle is one of the branches of this system. If conduction through the right bundle is slowed or blocked the parts of the heart it serves will contract late, seen as widening of the electrocardiographic qrs-wave. Unless the remainder of the conduction system fails, it usually isn't a problem. ...Read more
Usually not: Left bundle branch block (lbbb) develops when 2/3 electrical "wires" in the heart stop working. Many patients can have lbbb and no sx. Lbbb usually reflects aging of the heart but can be seen in a variety of pathological heart conditions. Rarely, medicines which affect the speed of electrical conduction in the heart can cause lbbb which reverses. This technically not cellular regeneration. ...Read moreSee 1 more doctor answer
Sometimes: A left bundle branch block is a finding on an EKG ( the electrical tracing of your heart.) it shows that something has altered the way your heart conducts electrical impulses. Chemotherapy can do it, but so can heart disease. Your doctor should rule out other causes for a left bundle branch block before assuming chemotherapy is the cause. ...Read moreSee 1 more doctor answer
Ecg : What you list are electrocardiographic patterns. Left atrial abnormality suggests the possibility of structural abnormalities of the left atrium. Incomplete right bundle branch block suggests slowing of electrical impulse conduction in the right bundle branch of the conduction system. These findings can be associated with abnormal structure and function but are not diagnostic any specific problem. ...Read more
Electrical slowing: The conduction of electricity in the lower chambers of the heart occurs through the left and right bundles. An incomplete right bundle branch block is an insignificant finding, representing a slight slowing in the electrical conduction as it passes through the right side of the heart. Please be aware that this has nothing to do with blockages in the arteries or heart attacks. ...Read moreSee 2 more doctor answers
