WebMar 12, 2024 · This electrical signal is produced by a tiny structure known as the sinus node, located in the upper portion of the right atrium. The right atrium is one of four heart chambers and related valves, which include two atria at the top of the heart with two ventricles at the bottom. 1 The cardiac electrical signal controls the heartbeat in two ways. WebThe valve separating the chambers on the left side of the heart valve is called the bicuspid or mitral valve. After it is filled, the right ventricle pumps the blood through the pulmonary arteries, by-passing the semilunar valve (or pulmonic valve) to the lungs for re-oxygenation.
