How Cardiac Conduction Works 🫀 In order for the heart to pump, an electrical signal travels down a specific path: ➡️ SA node – the pacemaker, starts the beat ➡️ AV node – delays so ventricles can fill ➡️ Bundle of His – carries the signal from the atria to the ventricles ➡️ Bundle branches – send it down right & left ventricles ➡️ Purkinje fibers – rapidly spreads the signal throguh the ventricles, leading to a contraction Having a solid baseline of how conduction normally works will help so mu

The heart’s electrical highway in action! ⚡This stunning visual of the cardiac conduction system (CCS) shows how every heartbeat is orchestrated. The latest JAHA review (May 2025) . unpacks cardiac conduction disorders in young adults—genetic vs. acquired causes, from Brugada syndrome to autoimmune triggers. it offers cutting-edge insights on ECG diagnostics, genetic screening, prevention strategies , and early intervention to prevent sudden cardiac events.
