Echocardiographic signs of LBBB M-mode: shows paradoxical septal motion — the septum moves inward early and then outward later in systole. 2D echo: demonstrates septal flash (brief early septal contraction), apical rocking (side-to-side movement of the apex), and delayed lateral wall contraction. Doppler: shows prolonged LV pre-ejection period and interventricular mechanical delay (aortic flow starts much later than pulmonary flow). Tissue Doppler (TDI): reveals septal-to-lateral delay in peak s

Which patient(s) have a LBBB? 👀🥚🌷 Can you "eye ball" dyssynchrony? In echocardiography, patients with LBBB often exhibit a biphasic or paradoxical septal motion due to delayed left ventricular activation. However, abnormal septal motion can also result from other conditions, such as pericardial constriction or volume overload, making it essential to differentiate between these patterns. Carefully examine the echocardiographic images and identify which patient(s) show findings consistent with

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

🎥 Classic Echo Finding: Apical Rocking 🔍 What you see here is a classic example of apical rocking, a striking echocardiographic sign. 🫀 When does it occur? It is typically observed in patients with left bundle branch block (LBBB). 📌 Why does it happen? Because of the abnormal sequence of ventricular activation in LBBB, the septum and lateral wall contract out of sync. This dyssynchrony leads to the characteristic “rocking” motion of the apex. 💡 Clinical Pearl: Apical rocking is not just a v
