Intraventricular conduction delay (IVCD) is a critical ECG finding, marked by a widened QRS complex (≥120 ms), reflecting delayed electrical conduction within the ventricles. Left bundle branch block (LBBB) is characterized by a deep S wave in lead V1, broad, single-peaked R waves in lateral leads (I, aVL, V5-V6), and a delayed R wave peak time (>60 ms in V5-V6), indicating left ventricular conduction impairment. Conversely, right bundle branch block (RBBB) presents with a QRS duration exceeding

Both of these rhythms show a wide QRS, but the conduction delay is on different sides of the heart 🫀 🔹 Right Bundle Branch Block (RBBB): • Delay in right ventricular conduction • RSR′ pattern (“bunny ears”) in V1 • Dominant R wave in V1 🔹 Left Bundle Branch Block (LBBB): • Delay in left ventricular conduction • Deep S wave in V1 • Broad, notched QRS in lateral leads 🧠 Quick recognition trick: Look at lead V1 Rotate the strip clockwise and whichever direction the QRS is pointing tells you the

AV Blocks – Progressive Conduction Failure: 1. First-Degree AV Block: Consistent delay at the AV node. Prolonged PR interval (>200 ms). Every impulse eventually reaches the ventricles. 2. Mobitz I (Wenckebach): Progressive PR interval lengthening until a P wave is blocked (a QRS is dropped). Typically at the AV node. Usually benign. 3. Mobitz II: Intermittent, sudden failure of conduction without preceding PR prolongation. Block typically infranodal (Bundle of His or below). Carries significant

🫀 Heart Blocks A heart block happens when there’s a delay or interruption in the electrical conduction that controls the heart’s rhythm. Here are the 4 types you need to know: 🔹 1st Degree → PR interval is prolonged 🔹 2nd Degree Type I (Wenckebach) → PR gets progressively longer, then drops a beat 🔹 2nd Degree Type II (Mobitz II) → PR is consistent, but some QRS complexes are randomly dropped ⚠️ Highest risk of progressing to 3rd degree 🔴 3rd Degree (Complete Heart Block) → No communication
