What is a bundle branch block?

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.

What is incomplete bundle branch block?

Mild conduction prob. The righty and left ventricles are induced to beat through electrochemical currents transmitted through the right and left bundle branches, respectively. Irbbb means part of the right bundle is not transmitting fully. It is a benign condition of no significant clinical consequence. Read more...

What is an incomplete bundle branch block?

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. Read more...
Slow conduction. The electrical activity in the bottom chambers of the heart take a certain range number of milliseconds to conduct (<120ms, commonly <100ms). If longer than 120, it represents a slowing in the system, called a bundle branch block. If there is an appearance of some delay in the conduction, but doesnt meet criteria (>120ms) for a full bundle branch block, it is an incomplete bundle branch block.. Read more...

What is a 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...

What does incomplete right bundle branch block indicate?

May be nothing. Incomplete right bundle branch block indicates a slight delay in the electrical conduction in the right bundle. It is often found on a routine ECG and almost always has no clinical consequences. Read more...
