The tertiary pacemaker is also known as the?
av node
What is the back-up pacemaker of the heart?
The sinoatrial node is known as the pacemaker of the heart.
What is called the reserve pacemaker?
av node
What is the hearts second pacemaker called?
AV node
What component of the heart's conduction system is considered to be the heart's pacemaker?
Furkinje Fibers
What pacemaker of the heart initiates depolarization under normal conditions?
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.
Where are the cells located that make up the pacemaker?
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.
How is the action of the pacemaker is related to the symptoms of heart block and fibrillation?
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.
Explain how the action of the pacemaker is related to the symptoms of heart block and fibrillation?
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.
Why the sino atria node is regarded as a pacemaker in the heart?
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.
Are the purkinje fibers commonly known as the natural pacemaker?
No, the purkinje fiber is not the natural pacemaker. The sinoatrial node (SA node) is the natural pacemaker of the heart.
Is the bundle of his is known as the natural pacemaker of the heart?
No, the Sinoatrial Node is known as the natural pacemaker of the heart
