Key medical terms in this context include the sinoatrial (SA) node, often called the natural pacemaker, and the atrioventricular (AV) node, which acts as a relay station to delay the signal slightly before it reaches the ventricles. Arrhythmias and Conduction Abnormalities Disorders of heart rhythm fall under the umbrella of arrhythmias, which have their own specific nomenclature.
Understanding Heart Electrical System Terms
Medical terms pertaining to the heart form a specialized vocabulary essential for accurately describing the structure, function, and pathology of this vital organ. The Myocardium and Conduction System Beyond the chambers lies the myocardium, the thick muscular wall of the heart responsible for its contractile force.
Valves ensure unidirectional flow, with the tricuspid and mitral valves controlling inflow between the atria and ventricles, while the pulmonary and aortic valves regulate outflow from the ventricles. Furthermore, the heart possesses an intrinsic electrical system that coordinates contraction.

Ischemia refers to a reduced blood supply to tissues, causing oxygen deprivation without necessarily resulting in cell death. Atrial fibrillation is a common irregular rhythm originating in the atria, increasing the risk of stroke.
