Left Bundle Branch Block ECG
1️⃣ Left Bundle Branch Block (LBBB) • ECG: Wide QRS complex (>120 ms), broad or notched R wave in leads I, V5–V6 • Echo effect: • The interventricular septum contracts early • The left ventricular free wall contracts late • Result: Jerky or paradoxical septal motion • 👉 Most common cause ⸻ 2️⃣ Right ventricular pacing (pacemaker rhythm) • ECG: Pacing spikes with an LBBB-like QRS morphology • Echo: • Abnormal electrical activation leading to septal dyssynchrony • Jerky septal motion is commonly

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
