Question 1

what is a bundle branch block?

Accepted Answer

Wiring: The heart is a muscle but how fast it beats is controlled by special cells, sort of like electric wiring. The main wire divides into two, one to the right and one to the left. If part of that wiring becomes abnormal you get a right or left bundle branch block. It results in a typical pattern on the ekg.

Question 2

is rt. bundle branch block reversible?

Accepted Answer

RBBB: Rbbb is generally benign. Some of its causes are reversible and some are not.

Question 3

what is an incomplete bundle branch block?

Accepted Answer

Not true "block": Two bundles of electrical tissue carry each heartbeat from the top part of the heart to the bottom--the "right" and "left" bundle branches. When one of these doesn't conduct at all, or does so much more slowly than the other, it is a complete bundle branch block. When one conducts slightly slower than the other, it is called "incomplete" bundle block. This often is of no clinical consequence.

Question 4

is bundle branch block a serious condition?

Accepted Answer

Yes: Bundle branch block is a significant abnormality that is typically discovered on an abnormal ECG (electrocardiogram) and should be further evaluated by a cardiologist.

Question 5

can certain medications cause bundle branch block?

Accepted Answer

BBB: Certaiin common blood pressure medications and/or antiarrhythmics in very high (not therapeutic) doses can cause bundle branch blocks. Digoxin is very well known to cause conduction abnormalities when in toxic levels.

Question 6

how do you confirm the presence of bundle branch block?

Accepted Answer

EKG: It is diagnosed by doing an ekg.

Question 7

what is the medical prognosis for a bundle branch block?

Accepted Answer

Right or left: If it is right bundle branch block then 98% is benign.  If it is left bundle branch block 95% are abnormal leading to further work up to rule out cardiomyopathy, conduction problems or coronary artery disease.

Question 8

is repetitive drug use the cause of a bundle branch block?

Accepted Answer

Depends, of course: Most cases of bundle branch block are due to a focal injury to a key part of the heart's electrical conduction system.  Coronary disease, scarring from trauma, infection, or natural processes can cause it.  Some illicit drugs, especially those creating coronary spasm (e.g., cocaine, amphetamines) may create those conditions, and frequent exposure (repetitive) only exacerbates the risk.

Question 9

what is the prognosis for an incomplete bundle branch block?

Accepted Answer

BBB: There are two types: right and left (irbbb and ilbbb). The right sided variety is usually benign and has no negative prognosis. The left variety may or may not indicate underlying heart problems. Discuss with your doctor.

Question 10

what is the definition or description of: bundle branch block?

Accepted Answer

Electrical blocks: 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 detected on an electrocardiogram.
