Is Fascicular block the same as bundle branch 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 bundle. The 2 disorders often coexist. There are usually no symptoms, but presence of either suggests a heart disorder. Diagnosis is by electrocardiography.
What is RBBB with left anterior fascicular block?
A left anterior fascicular block is the term for something interfering with your heartbeat's signal when it gets to the left anterior fascicle of your heart's left bundle branch. This makes your heart's left ventricle contract later than your heart's right ventricle.
What causes RBBB and LAFB?
RBBB + LAFB is the most common of the two patterns. This is due to a single coronary artery blood supply (LAD) to the anterior fascicle. RBBB + LPFB is less common due to a dual blood supply (right and left circumflex arteries), and this combination may be associated with more extensive underlying cardiac pathology.
Is left anterior fascicular block the same as left bundle branch block?
Left anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the left anterior fascicle – one half of the left bundle branch being defective.
