8 Οκτ 2024 · Bifascicular block is a conduction abnormality involving two of the three fascicles of the ventricles. It can be RBBB with LAFB or LPFB, and is often associated with structural heart disease and risk of complete heart block.

Bundle branch block is partial or complete interruption of impulse conduction in a bundle branch; fascicular block is similar interruption in a hemifascicle of the left bundle. The disorders often coexist. There are usually no symptoms, but presence of either suggests a heart disorder.
2 Μαΐ 2022 · A bifascicular block delays or stops electrical signals between the left and right bundle branches (fascicles). This problem affects your heart’s lower pumping chambers (ventricles), causing it to pump too slowly or out of rhythm (arrhythmia).
RBBB is a conduction defect that affects the right ventricle depolarization and repolarization. It is characterized by QRS duration ≥0,12 seconds, large R’-wave in V1/V2 and broad S-wave in V5/V6.
The most common bifascicular block is right bundle branch block with left anterior fascicular block (RBBB + LAFB). Left bundle branch block with simultaneous left posterior fascicular block (RBBB + LPFB) is uncommon.
13 Φεβ 2016 · When we have right bundle branch block with either left anterior fascicular block (common) or left posterior fascicular block (less common) we call it a bifascicular block. The problem with bifascicular block is that the heart’s electrical conduction system is down to one fascicle.
3 Νοε 2020 · Right bundle branch block (RBBB) RSR in V1 (‘M’), and ‘W’ in V6 (MARROW), normal axis. Left bundle branch block (LBBB) septal depolarisation reversed so there is a change in initial direction of QRS (WILLIAM), normal axis. Bifascicular block. RBBB + block of either left anterior or posterior fascicle. RBBB + left anterior fascicle block -> LAD.
