An artificial Pacemaker is a device that helps to regulate the beating of the heart through electrical impulses. When the rhythm of the heart is very slow or when there are long pauses between the heartbeats; after detecting those problems the pacemaker stimulates the heart.
As any other technological innovation, the artificial pacemaker helps to improve the quality of human’s life; for example the main diseases that a pacemaker solves are the cardiac arrhythmias which are irregularities in heart rhythm. Cardiac arrhythmias can cause to the patient some symptoms like weakness, fatigue, palpitations, low blood pressure, dizziness and fainting. Even worse than the previous symptoms cardiac arrhythmias can cause the patient’s dead. Taking in account all the previous information, this technological innovation saves many lifes and nowadays it is a very important device.
Since 1958, Jorge Reynolds, an electronic engineer that also discovered that the hearts of cetaceans are similar to humans, has been working in artificial pacemakers; in fact the first pacemaker's battery was Reynolds's own car, a Triumph sports car. Since then, he’s been working in it and recently he had created a new artificial pacemaker using nanotechnology and it does not need batteries.
Pacemakers of our time are the size of a matchbox and are used by more than 48 million people in the world.
Nevertheless, there are somthing that can afect them, like MRI machines, radiation machines used for cancer treatments, strong magnets and machines for weld.
