In order for the ventricles to contract, the His-Purkinje system (bundles of specialized nerves in the electrical conduction system) takes over as a natural pacemaker in the lower chambers.
WebIn third-degree SA block, impulse exit conduction is blocked; normal P waves are absent, giving the appearance of sinus arrest. Etiology of Sinus Node Dysfunction . The most common cause of sinus node dysfunction is . Idiopathic SA node fibrosis, which may be accompanied by degeneration of lower elements of the conducting system. WebThird-degree sinoatrial (SA) block. Third-degree sinoatrial block implies that no impulses are conducted from the sinoatrial node to the atrium. Hence, the maintenance of cardiac rhythm (and thus life) will depend on awakening of a latent pacemaker.
