UpToDate Left anterior fascicular block (LAFB) is a condition affecting the heart's electrical system, altering its normal activation sequence
Left anterior fascicular block - UpToDate The anatomy, clinical manifestations, differential diagnosis, prognostic implications, and treatment of LAFB will be reviewed here Additional details regarding the ECG manifestations of LAFB are discussed separately (See "ECG tutorial: Intraventricular block", section on 'Left anterior fascicular block' )
Q A: Symptoms Risks of Left Anterior Block - JustAnswer Left Anterior Fascicular Block (LAFB), also called left anterior hemiblock, is a condition where the electrical conduction through the anterior fascicle of the left bundle branch of the heart is delayed or blocked While it can be asymptomatic, it may cause fatigue, dizziness, shortness of breath, or palpitations in some individuals
Left Anterior Fascicular Block Treatment - JustAnswer What is a left anterior fascicular block? A left anterior fascicular block is known as a cardiac condition that may often be determined by a left bundle branch block In the case of the left bundle branch being defective, a left anterior fascicular block may be the result Left anterior fascicular block may however be noticeable on an ECG
ECG tutorial: Intraventricular block - UpToDate A left anterior fascicular block, or hemiblock, is characterized by left axis deviation of >-45° or >-60°, or, depending on the author, up to -90° (see "Left anterior fascicular block") This may be the result of conduction system disease in the anterior fascicle of the left bundle, or may occur when there is disease or fibrosis surrounding
Left septal fascicular block - UpToDate Left septal fascicular block (LSFB; also called left middle or left median fascicular block) results when one of the earliest phases of normal electrical activity in the His-Purkinje system is delayed or interrupted Since the normal sequence of activation is altered in LSFB, it may be associated with alteration in the electrocardiogram (ECG)

How serious is a right branch block and left anterior fascicular . . . The combination of a right bundle branch block (RBBB) and the left anterior fasciular block (LAFB) is known as a bifasicular block Generally no treatment is necessary, although in some cases this can progress to complete heart block which would require placement of a pacemaker

Medline ® Abstract for Reference 21 of Left anterior fascicular block Compared with no block, isolated left anterior fascicular block (LAFB) was associated with 0%-2% increased 10-year risk of developing third-degree AVB (HR 1 6; 95% confidence interval [CI]1 25-2 05), whereas right bundle branch block combined with LAFB and first-degree AVB was associated with up to 23% increased 10-year risk (HR 11 0; 95% CI 7
