WebThe SA (sinoatrial) node generates an electrical signal that causes the upper heart chambers (atria) to contract. The signal then passes through the AV (atrioventricular) node to the lower heart chambers (ventricles), causing them to contract, or pump. The SA node is considered the pacemaker of the heart.

WebJun 11, 2024 · Introduction. Arrhythmia is an abnormal rhythm of the heart. The only normal rhythm of the heart is a normal sinus rhythm. In this rhythm, an impulse is generated in the sinoatrial (SA) node, which is conducted through and slowed down while passing through the atrioventricular node (AV). WebSinoatrial (SA) block implies that the impulses discharged in the sinoatrial node are either not conducted to the atria or are so with a delay. This manifests with loss of P-waves (loss of atrial activation) and consequently loss of QRS complexes (loss of ventricular depolarization). Sinoatrial block is subdivided into three degrees according ...
