Subsequent, the signals arrive in a cluster of cells known as the atrioventricular (AV) node, wherever they decelerate. This slight hold off makes it possible for the ventricles to fill with blood. In the event the electrical signals reach the ventricles, the chambers contract and pump blood towards the lungs or to the rest of the entire body.
