• SA Node is the pacemaker for the heart. It is located on the upper posterior wall of the RA. It generates a stimuli at regular intervals (60-100 bpm), and it corresponds with the P WAVE on the ECG. • Intranodal pathways (between SA and AV nodes) • AV Node slows the impulse coming from the SA Node (recall that the AV is the “relay station”).

Hello Dear students! 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 .

This ensures the transportation of different substances in the circulatory medium; blood, which includes oxygen, nutrients, waste products, etc. The difference between SA node block and SA node suppression is that in SA node block an electrical impulse is generated by the SA node that doesn't make the atria contract. In SA node suppression, on the other hand, the SA node doesn't generate an electrical impulse because it is reset by the electrical impulse that enters the SA node.

The SA node generates its own action potentials, but may be influenced by the autonomic nervous system. Without autonomic nervous stimulation, the SA node will set the heart rate itself, acting as the primary pacemaker for the heart. The SA node is primarily innervated by the right vagus nerve. The SA node is typically perfused by the right coronary (RCA, 55-60%) & left circumflex arteries (LCx, 40-45%) in most people.
