Pacemakers

Introduction
What is a pacemaker?
A pacemaker is a small device that is placed inside the chest to help control abnormal heart beats. This device uses electrical pulses to prompt the heartbeat back to a normal heart rate.
Pacemakers help control Arrhythmia as you will read below. To explain, during Arrhythmia the heart may not be able to pump enough blood for the body. This can cause tiredness, a short breath, or even fainting. For example it could cause a loss of consciousness or death. These heart problems can go in many life depending paths.A famous person with a pacemaker
Facts
The pacemaker was invented by Wilson Greatbatch. Also for more information, A heartbeat that is too fast is called Tachycardia and a heartbeat that is too slow is called Bradycardia. And Arrhythmia is a problem with the rate of your heart or your rhythm of the heartbeat. During Arrhythmia, your heart can beat too fast, too slow, or with a different rhythm than usual. Also A resting heart rate means that that's the heart rate when you are resting, so a resting heart rate for 10 and older, (including adults) is around 60 to 100 beats a minute. But for children a resting heart rate is all different…
Children from 3 to 4 years old = 80 to 120 beats every minute, children from 5 to 6 years old = 75 to 115 beats every minute, children from 7 to 9 years old = 70 to 110 beats every minute.Conclusion
