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.

What does a pacemaker control in the heart?
A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
What is the function of your natural pacemaker?
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.
What is the name of rate set by the heart's pacmaker?
Sinus rhythm
What is the difference between a fixed rate pacemaker and a demand pacemaker?
A fixed-rate pacemaker sends electrical prompts to your heart at an unchanging rate. Its drawbacks include that it is somewhat difficult to adapt to a state of physical exertion or emotional arousal.A more advanced type, called a demand pacemaker (there are several types) kicks in after your cardiac function varies outside a pre-set normal rate. It then brings your heartbeat into a more efficient rhythm. (Sinus-rhythm.)A demand pacemaker does not take the place of an implanted defibrillator! If a lifethreatening cardiac arrhythmia develops, it takes a defibrillator -- an implanted one or an external unit used by someone trained to respond -- to correct ventricular fibrillation. If it is not corrected, v-fib is fatal.Demand pacemakes are used to restore a normal heart rate that only becomes abnormal occasionally. A fixed rate pacemaker is used when the problem is always there and the heart won't keep going without constant help.

How does pacemaker help?
Most common use of a pacemaker is to have it help the heart keep its rhytm, but they can also be set up to act as a an integrated defibrillator to shock start the heart if it should stop.
What especial equipment is connected to the heart to make it beat?
When the SA node in your heart stops functioning properly, then you have to receive a pacemaker, which will take the place of the SA node and set your heart beat for you.
The rate and pace of the heart is set by what?
The rate and pace of the heart are set by the SA node. There are backup systems in place if the SA node fails to do its job.
What is pacemaker of the heart is the?
The pacemaker of the heart is a bundle of cells that tells the heart when to beat. These cells are connected to the rest of the cells of the heart and communicate with them through electrical signals. The pacemaker cells set the pace (or rate) of the heartbeat.The actual structure that serves as the heart's primary pacemaker is called the sinoatrial node (SA node). As described above, the SA node is a little bundle of cells located in the wall of the right atrium, the small upper chamber on the right side of the heart.What if the SA node is knocked out for some reason? There are actually other regions of the heart that can act as pacemakers. These regions are known as latent pacemakers and include the atrioventricular node (AV node) and other cells that make up the electrical communication system of the heart (including special cells that make up the so-called Purkinje fibers of the heart). Even the cells that make up the large ventricles of the heart can set the pace of the heart.Interestingly, each of the pacemakers described above has a different inherent rate that it "wants" the heart to beat at. For example, the SA node gets excited spontaneously at a rate of about 100 per minute. Some of the latent pacemakers might spontaneously get excited at a rate of 65 per minute or 45 per minute.If that's the case, then wouldn't the heart just beat chaotically? How is it possible that the heart beats in a regular way with all of these different pacemakers lying around?The reason is that under normal circumstances, only the SA node is active; all of the other latent pacemakers are basically inactive. Now, should the SA node fail, the AV node can take over. Likewise, if the AV node fails, cells that make up the Purkinje fibers can take over. And if even they fail, then the ventricular cells can take over as a last resort. There's lots of redundancy for this all-important organ.Another type of pacemaker is the type that gets implanted by physicians. In patients with abnormal heart rates or rhythms, an artificial pacemaker can be implanted. These pacemakers serve the same purpose as the natural pacemakers of the heart: they control the regular rate and rhythm of the heart.
What cells set the heart rate?
answer it ya self feck head
What ventricle is the pacemaker?
this is a particular setting on a pacemaker which essentially senses if the ventricle depolarises, if it does not the PM will activate it and ensure the heart carries on beating.Also:A demand pacemaker (there are several types) kicks in after your cardiac function varies outside a pre-set normal rate. It then brings your heartbeat into a more efficient rhythm. (Sinus-rhythm.)A demand pacemaker does not take the place of an implanted defibrillator! If a genuinely life-threatening cardiac arrhythmia develops, it takes a defibrillator -- an implanted one or an external unit used by someone trained to respond -- to correct ventricular fibrillation. If it is not corrected, v-fib is fatal.
What conducting cells set heart rate?
Sinoatrial Node (SA node)
