⚡The Heart’s Symphony: Conduction System & NSR⚡ Every heartbeat is a masterpiece conducted by these key players: ✅ SA Node – The natural pacemaker (60-100 bpm). ⏳ AV Node – Delays the signal to let atria contract. 🥢Bundle of His/Branches – High-speed highways to ventricles. 💥 Purkinje Fibers – Trigger synchronized ventricular pumping! NSR = Normal Sinus Rhythm 🌟 When this system fires perfectly, you get that beautiful, steady lub-dub we all love! #Cardiology #HeartConduction #MedicalVisuals #
