Your heart is a pump that sends blood through your body. For each heartbeat, electrical signals travel through the conduction pathway of your heart. It starts when your sinoatrial (SA) node creates an excitation signal. This electrical signal is like electricity traveling through wires to an appliance in your home. The excitation signal travels to: Your atria (top heart chambers), telling them to contract. The atrioventricular (AV) node, delaying the signal until your atria are empty of blood. The bundle of His (center bundle of nerve fibers), carrying the signal to the Purkinje fibers. The Purkinje fibers to your ventricles (bottom heart chambers), causing them to contract. These steps make up one full contraction of your heart muscle. Your heart conduction system sends out thousands of signals per day to keep your heart beating. What conditions and disorders affect electrical conduction in your heart? Several different conditions can affect your heart’s electrical system. These problems cause issues with your heart’s rhythm. Some common heart rhythm disorders include: Arrhythmia Bundle branch block Heart block Long Q-T syndrome (LQTS) Premature ventricular contractions Sudden cardiac arrest ❗ATTENTION❗: The information provided in this video lecture is purely educational, please follow your hospitals or organizations guidelines and policies.
