Left Anterior Fascicular Block (LAFB) EXPLAINED: ECG Criteria & QRS Changes (Beginner’s Guide)

⚡ Left Anterior Fascicular Block (LAFB): ECG Criteria & QRS Changes Explained Left Anterior Fascicular Block (LAFB), also called left anterior hemiblock, is a conduction abnormality affecting the anterior fascicle of the left bundle branch, leading to left axis deviation and characteristic ECG findings. But what causes LAFB, and how can it be identified on ECG? This video provides a high-yield breakdown of LAFB pathophysiology, ECG criteria, depolarization sequence changes, and clinical significance, perfect for medical students, ECG technicians, USMLE prep, and cardiology professionals. What You’ll Learn in This Video: ✔️ What is Left Anterior Fascicular Block (LAFB)? ✔️ How LAFB affects left ventricular depolarization and QRS morphology ✔️ ECG Criteria: Left axis deviation, small Q waves in leads I & aVL, tall R waves in aVR ✔️ Depolarization Changes: Delayed activation of the anterolateral LV ✔️ LAFB vs. Left Posterior Fascicular Block (LPFB): Key ECG Differences ✔️ Clinical Significance: When LAFB is benign vs. a marker of heart disease ✔️ High-yield mnemonics & USMLE exam pearls https://t.me/foxterRier_med #usmle #step1 #step2 #medicine #pathology #physiology #education #medicalschool #pharmacology #biochemistry #highyield #lab #ecg #ecginterpretation #cardiology #LAFB #depolarization #block
