Ventricular Escape Rhythm: A Life-Saving Default 🫀 When higher pacemakers fail, the ventricles initiate a protective escape rhythm. Understanding this backup system is crucial for emergency cardiac care. ⚙️ Conduction Hierarchy & Rates: •SA Node: 60-100 bpm (Primary) •AV Node: 40-60 bpm (Junctional) •Ventricles: 20-40 bpm (Escape) 🚨 Emerges When: Supraventricular impulse rate falls below intrinsic ventricular rate ⚠️ Common Causes: •Complete AV Block •Sinus Arrest/Exit Block •Drug Toxicity (BB
