2025年2月18日 · In left anterior fascicular block (LAFB), impulses are conducted to the left ventricle via the posterior fascicle, producing characteristic ECG changes

2022年5月24日 · A left anterior fascicular block diagnosis may be benign, but researchers found that people with left anterior fascicular block have a higher risk of congestive heart failure, …

2024年11月18日 · Left anterior fascicular block (LAFB), a pattern (formerly called left anterior hemiblock) seen on the surface electrocardiogram (ECG), results when normal electrical activity in the His-Purkinje system is delayed or interrupted.

LAFB — which is also known as left anterior hemiblock (LAHB) — occurs when a cardiac impulse spreads first through the left posterior fascicle, causing a delay in activation of the anterior and upper parts of the LV.

Learn about left anterior fascicular block (hemiblock) and left posterior fascicular block, with emphasis on ECG criteria, causes, effects and management.

What is a Left Anterior Fascicular Block? A Left Anterior Fascicular Block (LAFB) is a problem with how electrical signals move in the heart. It affects the left anterior fascicle, a key part of the heart’s bundle branches. This part helps make sure the heart beats in sync. The heart needs a special network to keep its rhythm steady.

Learn about the causes, symptoms, and diagnosis of left anterior fascicular block (LAFB), a common ECG finding in heart evaluations.

The criteria to diagnose a LAFB, or LAHB, on ECG include the following: A very quick way to diagnose a left anterior fascicular block on ECG is to first identify the left axis deviation;...

2015年9月14日 · LAFB can have many causes, including myocardial infarction, cardiomyopathies, fibrosis of the cartilagenous ring, and aortic valve disease. Left anterior fascicular block is much more common than left posterior fascicular block. Both are also called hemiblocks.

2025年3月17日 · The main change of left hemiblocks in the electrocardiogram is a marked deviation of QRS axis. Left anterior fascicular block has a marked left axis eviation and left posterior fascicular block has a marked right axis deviation (see how to determine the heart axis).
