A recording of electrical changes occurring in the myocardium during the cardiac cycle. Introduction: The set of atrial contractions while the ventricular muscles relax, followed by ventricular contractions while the atrial walls relax, constitutes a cardiac cycle. Each cycle generates pressure changes within the heart chambers, resulting in the ejection of blood. Movement only occurs in one direction due to one-way valves present in the chambers.
