Normal Sinus Rhythm: Electrophysiology, EKG Characteristics, and Cardiac Homeostasis
1. Introduction Normal sinus rhythm is the fundamental, healthy electrical pattern that dictates the mechanical beating of the human heart. It is the physiological baseline of cardiovascular function, ensuring that the heart chambers contract in a perfectly coordinated, highly efficient sequence. This rhythmic electrical propagation guarantees that deoxygenated blood is pumped smoothly to the lungs … Read more
