No, it is the SAN (sinoatrial node)
av node
The sinoatrial node is known as the pacemaker of the heart.
av node
AV node
Furkinje Fibers
The intrinsic rate of the AV node, also known as the inherent pacemaker rate, is the rate at which the AV node generates electrical impulses when not influenced by outside factors. It is typically around 40-60 beats per minute and serves as a backup pacemaker if the SA node fails to function properly. The AV node's intrinsic rate helps to regulate the heart rate and maintain cardiac function.
The primary pacemaker of the mammalian heart is the sino-atrial node. If the SA node fails, the atrioventricular node (AV node) takes over pacemaking.
If you mean the heart, there are two pacemakers. One is in the SA Node and the secondary (and slower) back up pacemaker is in a AV Node.
In a Cardiac condition known as heart block, there is an interruption in the message from the SA node to the AV node. The interruption can occur in varying degrees.
The sinoatrial, or SA, node is known as the pacemaker of the heart. There are other potential pacemakers if the SA node fails, but it is the main pacemaker.
In a Cardiac condition known as heart block, there is an interruption in the message from the SA node to the AV node. The interruption can occur in varying degrees.
No, the purkinje fiber is not the natural pacemaker. The sinoatrial node (SA node) is the natural pacemaker of the heart.
