It describes how the atria and ventricles fill, contract, and relax with each heartbeat. It is a core physiology concept used across cardiology, including bedside examination, echocardiography, electrocardiography (ECG), and hemodynamics. It is commonly referenced when interpreting heart sounds, murmurs, blood pressure, and ventricular function."}
