Purkinje's System, also known as the cardiac conduction system, is responsible for coordinating and regulating the heartbeat. The system consists of specialized cells in the heart that generate electrical impulses to ensure the synchronized contraction of the heart muscles. There are several synonyms for Purkinje's System, including the sinoatrial node, atrioventricular node, bundle of His, and the Purkinje fibers. The sinoatrial node is located in the right atrium of the heart and initiates electrical impulses, while the atrioventricular node regulates the rate of impulses. The bundle of His conducts the impulses to the Purkinje fibers, which are responsible for the contraction of the ventricles. Understanding these synonyms for Purkinje's System is crucial to diagnosing and treating heart conditions.
