Where is SA node and AV node located?

The atrioventricular node lies on the right side of the partition that divides the atria, near the bottom of the right atrium. When the impulses generated by the SA node reach the AV node, they are delayed for about a tenth of a second.

Herein, where is the AV node located?

The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.

Also, how does the SA node and AV node control heart rate? The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The SA node sets the rate and rhythm of your heartbeat. Normal heart rhythm is often called normal sinus rhythm because the SA (sinus) node fires regularly. AV node (atrioventricular node).

Moreover, what is the difference between SA node and AV node?

The SA (sinoatrial) node generates an electrical signal that causes the upper heart chambers (atria) to contract. The signal then passes through the AV (atrioventricular) node to the lower heart chambers (ventricles), causing them to contract, or pump. The SA node is considered the pacemaker of the heart.

What connects the SA node to the AV node?

More specifically, the anterior tract is described as extending from the anterior part of the sinoatrial node, bifurcating into the so-called Bachmann’s bundle which importantly delivers impulses to the left atrium and with a second tract that descends along the interatrial septum that connects to the anterior part of
