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.
The Pacemaker
Valves have nothing to do with heart beat The pacemaker of the heart controls the heart beat
An Artificial Pacemaker basically regulates the rate of the heart beat depending on the needs of the body.
An artificial 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.
pacemaker controlls the heart beat and etc
The heart itself tells the heart to beat. It contains a small cluster of nerves that act as a biological "pacemaker".
A pacemaker takes the place of a persons actual heart. It pumps the blood through your body like a regular heart does. The rythem of the beat and the rate of the beat can be monitored and adjusted if the person's body does not react to it correctly.
Putting it into simple terms, a pacemaker helps the heart beat whereas a defibrillator stops the heart for a moment. Pacemakers generate electrical activity in the heart for patients with certain cardiac arrythmias. A defibrillator actually generates a shock so strong that it stops the heart's electrical activity. The heart (unlike most muscles) generates its own electrical impulse and can therefore hopefully restart itself after this big shock. Defibrillators are usually used for more serious cardiac arrythmias.Yes, a very big difference:a defibrillator is used to stop a heart that is beating in a random rhythm without moving blood in a pattern called Ventricular Fibrillation, to do this the defibrillator applies a single large shock which stops the heart completely briefly then the heart (usually) self starts with a normal rhythm that moves blood as it should; if the heart restarts in the random rhythm it will be necessary to repeat the single large shocka pacemaker is used to keep a heart beating with a normal rhythm that sometimes "forgets" to beat by applying small periodic shocks all the time at the pace of the normal rhythm
artificial pacemaker
Pacemakers regulate the heart beat. They are very safe.
