The atrioventricular node delays impulses by approximately 0.09s. This delay in the cardiac pulse is extremely important: It ensures that the atria have ejected their blood into the ventricles first before …

Oct 30, 2023 · The atrioventricular node is the second of several components of the cardiac conduction system. This intrinsic conduction system is responsible for generating impulses for the contractions …

Jun 26, 2025 · The anatomical arrangement of the atrioventricular node has been likened to a riddle wrapped up in an enigma. There are several reasons for this alleged mystery, not least the marked …

Apr 15, 2023 · The atrioventricular node (AV node) is a specialized tissue in the heart that plays a crucial role in regulating the electrical impulses that control the heart's contractions.

The atrioventricular node (or AV node) is located in the base of the right atrium close to the interatrial septum. The AV node is a group of highly specialized cardiac muscle fibers that depolarize and …

Dec 19, 2025 · The atrioventricular (AV) node is a group of specialized pacemaker cells that connect and coordinate contraction between the atria and the ventricles of the heart. It is an important part of …

Aug 22, 2025 · The atrioventricular (AV) node is a small structure within the heart’s electrical system. It coordinates each heartbeat by controlling the transmission of electrical signals from the upper …

Jun 18, 2025 · Explore the intricate functions and significance of the atrioventricular node in cardiac physiology. Understand its role in heart rhythm management.

In the normal fetal heart, the two atrioventricular valves are within the diaphragmatic plane of the heart. Usually, twisting of the atrioventricular connections occurs in a direction that places the …

Atrioventricular block is a heart rhythm disorder that causes the heart to beat more slowly than it should. It’s caused by communication problems within the heart’s electrical conduction system. For some …
