2. Cardiac conduction system - Wikipedia

   en.wikipedia.org/wiki/Cardiac_conduction_system

   Graphical representation of the electrical conduction system of the heart that maintains the heart rate in the cardiac cycle. Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum.

3. Atrioventricular node - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_node

   Isolated heart conduction system showing atrioventricular node. The AV node receives two inputs from the right atrium: posteriorly, via the crista terminalis, and anteriorly, via the interatrial septum. [8] Contraction of heart muscle cells requires depolarization and repolarization of their cell membranes. Movement of ions across cell ...

6. Cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Cardiac_pacemaker

   Image showing the cardiac pacemaker or SA node, the primary pacemaker within the electrical conduction system of the heart The cardiac pacemaker is the heart 's natural rhythm generator. It employs pacemaker cells that produce electrical impulses, known as cardiac action potentials , which control the rate of contraction of the cardiac muscle ...

8. Bundle of His - Wikipedia

   en.wikipedia.org/wiki/Bundle_of_His

   The bundle of His (BH) [1]: 58 or His bundle (HB) [1]: 232 (/ h ɪ s / "hiss" [2]) is a collection of heart muscle cells specialized for electrical conduction.As part of the electrical conduction system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the ...

9. Sinoatrial node - Wikipedia

   en.wikipedia.org/wiki/Sinoatrial_node

   These cells produce an electrical impulse known as a cardiac action potential that travels through the electrical conduction system of the heart, causing it to contract. In a healthy heart, the SA node continuously produces action potentials, setting the rhythm of the heart (sinus rhythm), and so is known as the heart's natural pacemaker.
