SA node is called as pacemaker. SA node beats at the rate of about 70 to 80 beats per minute. The cells from the atria beats at the rate of 50 to 60 beats per minute. Same or some what lower is rate for AV node. The bundle of His ( means of God) beat at still lower rate. The cells from ventricles beat at 30 to 40 beats per minute. So the SA node or pace maker decides the rate of contraction and heart beats in coordinated manner. Other wise you would have landed up in atrial and ventricular fibrillation. You have ineffective heart contraction in fibrillation. You die in no time in ventricular fibrillation, unless you get DC shock.

What is the function of your natural pacemaker?

Are the purjinke fibers the hearts pacemaker?
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.
