LAFB
Results:
Fascicular Blocks
Key Points Definition: Delay/block within the left bundle’s fascicles—left anterior (LAF) or left posterior (LPF)—alters ventricular activation and the QRS axis. Types: LAFB (common) → left axis deviation; LPFB (rare)…
Left Anterior Fascicular Block (LAFB)
Key Points Mechanism: Block in the left anterior fascicle → ventricular activation proceeds down the left posterior fascicle, then spreads inferior-to-superior and right-to-left across the LV. ECG signature: Left axis…
