A clear visual guide to differentiating Left Bundle Branch Block (LBBB) and Right Bundle Branch Block (RBBB) on ECG. Key features at a glance: ◾️ LBBB (Left Bundle Block): · Dominant S in V1 · Broad monophasic R in lateral leads (I, aVL, V5-6) · No Q waves laterally · QRS > 120ms ◾️ RBBB (Right Bundle Block): · RSR' pattern in V1-3 ("M-shaped") · Wide, slurred S wave in lateral leads · QRS > 120ms Essential for quick, accurate interpretation. This visual breaks it down. Save. Share. Know. ⚡✨ #Ca

Bundle Branch Block Patterns in ECG! 📊 LBBB: QRS ≥ 120ms, dominant S wave in V1, broad monophasic R wave in lateral leads (I, aVL, V5-6), no Q waves, prolonged R peak time > 60ms in V5-6. RBBB: QRS > 120ms, RSR' pattern in V1-3, "M-shaped" QRS, wide slurred S wave in lateral leads (I, aVL, V5-6). #ecg #bundlebranch #lbbb #rbbb #heartdisease | Abdallah Othman

Left Bundle Branch Block (LBBB) Overview 🔍 Etiology: Fibrosis/degeneration (e.g., age-related), myocardial pathology, left bundle branch compression. 💡 Risk Factors: Coronary artery disease, hypertension, valvular heart disease, cardiomyopathy. 📊 ECG Features: Widened QRS, notched R waves (V5-V6), deep S wave (V1).#Cardiology #Healthcare #BundleBranchBlock #ECG #MedicalEducation | Abdallah Othman
