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 · What is 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.

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.

Block in the anterior fascicle causes left anterior fascicular block (LAFB). Block in the posterior fascicle causes left posterior fascicular block (LPFB). In a fascicular block, the myocardium without fascicular supply will depend on impulses spreading from other parts of the ventricle (where the fascicle is intact). Figure 1.

2013年4月11日 · A cardiac condition called left anterior fascicular block (LAFB), in which scarring occurs in a section of the left ventricle, may not be as benign as currently thought and could increase the likelihood of heart failure, sudden cardiac death or atrial fibrillation.

Left anterior fascicular block (LAFB) commonly presents with symptoms such as dizziness, fainting spells or syncope, shortness of breath, palpitations, and heart failure. These symptoms arise because of a disruption in the left bundle branch system, leading to delayed contraction of the left ventricle.

左前分支阻滞(left anterior fascicular block, LAFB)是希氏-浦肯野系统的正常电活动延迟或中断导致的体表心电图改变，以前称左前半支阻滞。LAFB的正常激动顺序改变，导致典型心电图表现，伴电轴明显左偏 。

Left anterior fascicular block or LAFB also known left anterior hemiblock, is a heart disease in which scarring occurs in a section of the left ventricle identifiable from an abnormal electrocardiogram (ECG). LAFB occurs when the anterior fascicle of the left bundle branch is unable to conduct electrical signals.

left anterior fascicular block (LAFB) is when there is non-conduction of the cardiac impulse down the left anterior fascicle; LAFB, also known as left anterior hemiblock, is more common than left posterior fascicular block; in LAFB the cardiac impulse spreads first through the left posterior fascicle (inferiorly).
