The contraction of heart (cardiac) muscle in all animals with hearts is initiated by chemical impulses. The rate at which these impulses fire controls the heart rate. The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.
No, the purkinje fiber is not the natural pacemaker. The sinoatrial node (SA node) is the natural pacemaker of the heart.
The SA node, the natural pacemaker of the heart, is found in the right atrium of the heart.
No, the Sinoatrial Node is known as the natural pacemaker of the heart
The essential function that keeps the heart pumping is the contraction and relaxation of the heart muscle, which is controlled by electrical signals from the heart's natural pacemaker, the sinoatrial node.

The property of the normal pacemaker region is able to provide a normal setting for the heart to beat. It allows the heart to beat at a regular rate.
Pacemakers are set by the surgeon-physician at the time it is implanted. Most times, the pacemaker is simply set to a normal heart rate (around 70-80 beats per minute). The primary function of the pacemaker is to restore a more regular beat when the heart cannot maintain a normal heart rate. You should consult your physician-surgeon for particulars about your pacemaker, its use, function, and signs/symptoms to watch for after the pacemaker is implanted.
A pacemaker is typically required for heart rhythms that are too slow (bradycardia) or irregular, such as complete heart block or symptomatic sinus node dysfunction. Conditions like atrial fibrillation with a slow ventricular response or certain types of congenital heart block may also necessitate a pacemaker. In general, when the heart's natural pacing system fails to maintain an adequate heart rate or rhythm, a pacemaker can help restore proper function.
Because TENS may interfere with pacemaker function, patients with pacemakers should consult a cardiologist before using a TENS unit
It keeps your heart at a steady pace.
No, you cannot feel the impulses from a pacemaker. A pacemaker generates electrical impulses to regulate the heartbeat, but these impulses are delivered directly to the heart muscle and are not perceptible to the individual. Most people with a pacemaker do not experience any sensation from its operation, although they may notice improvements in their heart function and overall well-being.
