WebDescribe how a heartbeat is initiated and coordinated? The sinoatrial node (SAN) sends a wave of electrical activity across the atria causing atrial contraction. The non-conducting tissue stops the immediate contraction of the ventricles. The atrioventricular node (AVN) delays the impulse whilst the blood leaves the atria and fills the ventricles.
