1 Its job is to help coordinate the contraction of the atria and the ventricles in … Easily learn the conduction system of the heart using this step-by-step labeled diagram. The cardiac conduction system is the electrical pathway of the heart that includes, in order, the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers. Learn about pacemaker cells and cardiac ac The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.It electrically connects the atria and ventricles. The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, and conducts the normal electrical impulse from the atria to the ventricles. EKG-2 (Rhythms of SA node, atria, AV node, ventricles, & heart blocks) study guide by nathan_barnhurst includes 63 questions covering vocabulary, terms and more.

The synchronized electrical sequence of the heart is initiated by the SA node, the heart's natural pacemaker. The firing of the SA node sends out an electrical impulse via its neurons to the right atrium, left atrium, and AV node simultaneously.
node (SA) is the fastest. In normal hearts, the SA node is the pacemaker. The other conduction tissue (AV node, bundle of His and Purkinje fibers) will take over as pacemakers in disease states according to their speed of depolarization (AV > bundle of His > Purkinje fibers). Heart rate (HR) can be modulated by autonomic nervous stimulation.
The yellow tunnel represents the AV node.
The AV node is responsible for most of the delay between the P wave and the QRS complex. On the intracardiac electrogram, the delay in the AV node is represented by the P wave to His bundle spike interval (the A—H interval). Disturbances of AV nodal conduction result in prolongation of the A—H interval. If the SA node fails to initialize, the AV junction can take over as the main pacemaker of the heart.

Welcome to my channel ''Dr Hafiz sultan academyThis is Dr Hadi Gold medalist and Mphil Lecturer Pharmacy Department University of Baloc In SA exit block, the SA node depolarizes, but conduction of impulses to atrial tissue is impaired. In 1st-degree SA block, the SA node impulse is merely slowed, and ECG is normal. The SA node at rest fires 60 to 100 times in adults per minute and 60 to 190 times per minute in infants and children (depending on the age and level of activity) while the junctional tissue about the AV node (cardiac backup pacemaker) fires 40 to 60 times per minute in the adult and 50 to 80 times per minute in children younger than 3. delay at the AV Node (AV conduction time) Ventricular depolarization : Interval between ventricular depolarization and repolarization .
