When the sinus node generates an electrical impulse, the surrounding cells of the right atrium depolarize. Then the cells of the left atrium, the AV (atrioventricular)node, follow, and at last the ventricles are stimulated via the His bundle. With this knowledge it is quite simple to recognize normal sinus rhythm on the ECG. Sinoatrial block (SA block): from ECG to clinical management Sinoatrial (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).

A normal heart rhythm is initiated in the sinus node of the cardiac conduction system.
