SA node (sinoatrial) is primary pacemaker, SV node (sinoventricular) is secondary. Purkinje fibers are the very last pacemaker on the list. If a heart gets down to firing on that it, the person is just about dead and needs IMMEDIATE medical attention. Its max rate per minute is 30. A normal heart rate is b/n 60-100 beats per minute.

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.
What is the hearts second pacemaker called?
AV node
What is the pacemaker for the entire myocardium?
The pacemaker of the entire myocardium is the: a) Atrioventricular junction b) bundle of his c) Purkinje fibers d) Sinoatrial node
The actual contraction of the ventricles of the heart is stimulated by?
Sinoatrial (SA) Node or "Pacemaker"
What is the function of the hearts pacemaker?
In the pulmonary circulation what is the correct order structures through which blood travels?
What component of the heart's conduction system is considered to be the heart's pacemaker?
Furkinje Fibers
What is the role of Purkinje fibres in the heart?
The Purkinje fibers work with the sinoatrial node to enable consistency in the contractions of the heart.Purkinje fibers are muscle fibers in the heart. They relay the contraction impulses from the bundle to the myocardium of the ventricles.Purkinje fibres transmit the signal that tells the heart to beat from the pacemakers to the heart muscle. They are even capable of generating their own signal if the pacemaker is damaged.
What is the main pace maker of the heart?
The primary pacemaker of a normal healthy heart is the sinus node (or SA node). It is located in the right atria of the heart.
What are the 3 pacemaker of the heart?
The three components of a pacemaker are the pulse generator, pacing lead and the programmer. The pulse generator is like the brain of the heart. It controls everything.The pacing lead stimulates the heart to beat. The programmer enables the physician to evaluate the pacemaker's performance and change settings without surgery.
