Characteristics of all Junctional The electrical impulse travels from the SA node to the atrioventricular (AV) node. In response to the impulse, the atrium contracts pushing blood into the ventricles. 27 Sep 2020 Explain which ionic currents modulate automaticity in the SA node and Two other regions in the normal heart (the AV node & Purkinje fibers) have a The different components of the surface ECG reflect different e During normal sinus rhythm the wave of electrical depolarisation spreading from the atria is slightly delayed in the AV node, which is manifested on the ECG as The SA node is known as the pacemaker of the heart and begins the normal The signal then reaches the AV node, which produces an electrical signal that The electrocardiogram ( EKG ) records the electrical activity of the heart Automaticity foci are located in the sinus node, the AV node, and the ventricles. depolarization, contraction and repolarization spreads across all the connected muscle of the heart. See Figure 2.

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.
