The internodal pathway is located between the axon and the dendrite of a neuron. It is responsible for transmitting information between the two structures.
Can left bundle branch block cause AFIB?
Left bundle branch block (LBBB) is a type of heart block that can cause atrial fibrillation (AFIB). LBBB occurs when the left bundle branch, which carries electrical signals from the heart’s upper chambers (the atria) to the lower chambers (the ventricles), is blocked. This can disrupt the normal flow of electrical signals through the heart, which can lead to AFIB.

The SAN and AVN are located in the right atrium of the heart. The SAN is located near the top of the atrium, and the AVN is located near the bottom.
What causes the AV node delay?
The AV node delay is caused by the time it takes for the electrical signal to travel from the atria to the ventricles. This delay is necessary to allow the atria time to contract and empty their blood into the ventricles.
During which phase of the cardiac cycle does the mitral valve open?
The mitral valve opens during the diastolic phase of the cardiac cycle. This is when the heart is relaxing and blood is flowing from the atria to the ventricles.
Where is the SA and AV node located?
The SA node is located in the right atrium, and the AV node is located in the lower part of the right atrium.

Why is there a 0.1 second delay at the AV node?
The AV node is a specialized conduction pathway in the heart that delays the spread of electrical activity from the atria to the ventricles. This delay is important because it allows time for the atria to contract and empty their blood into the ventricles. The delay is caused by the presence of a small number of cells in the AV node that can resist the passage of an electrical current. This resistance slows down the spread of electrical activity and results in a 0.
Where is the AV node in the heart?
The AV node is located in the lower part of the right atrium, near where the atria and ventricles meet.
What would happen if the AV bundle bundle of His was damaged?
The AV bundle is a collection of cardiac muscle fibers in the heart that conducts electrical impulses. If this bundle is damaged, it can cause arrhythmias or irregular heartbeats.
What is the difference between the AV node and the SA node?
The AV node is responsible for slowing down the electrical signal that travels from the atria to the ventricles. This gives the ventricles time to fill with blood before the signal is sent. The SA node is responsible for setting the rhythm of the heart.
Why does the AVN have a short delay?
There are a few reasons for the AVN’s delay. One reason is that the AVN takes into account a variety of factors when calculating the best route for a flight, such as weather conditions and airport traffic. Another reason is that the AVN needs time to receive updated information about those conditions. Finally, it takes time to input all that information into the system and ensure that it’s accurate.
At which time is blood flowing into the aorta?
The aorta is the main artery in the body that carries oxygenated blood from the heart to the rest of the body. Blood flow into the aorta begins when the left ventricle of the heart contracts and pushes blood into the aorta.
