'pacemaker' is a correct and usable word in written English.
You can use it when talking about an artificial device that is used to regulate and normalize a patient's heartbeat. For example: "His doctor recommended that he have a pacemaker installed to regulate his heart rate."
A diabetic, Di Stéfano underwent a quadruple aorta-coronary bypass with a pacemaker implanted in December 2005 after suffering a myocardial infarction.
"In London I was attempting around 1 41.00 without a pacemaker, although I knew that no one had ever done that.
This, in turn, ensures that the current remains more or less the same, regardless of how quickly or slowly the heart is beating.Dr Karami's piezoelectric generator produced more than 20 times the power needed to keep the pacemaker ticking at normal heart rates.
Those earlier efforts stumbled, however, because the piezoelectric components were only able to harvest enough energy to power a pacemaker if the vibrations fell within a narrow frequency range.
IN 1958 a priest named Gerardo Flórez, then 70 years old, was blessed with the world's first artificial pacemaker.
Its aim is not to shock the heart to restore its normal rhythm, as an implantable cardioverter-defibrillator would do, but to hold enough charge to keep the pacemaker running while doctors try to revive the patient using an external defibrillator.Tests in pigs and sheep look promising.
Some designs beam energy to a receiving coil in an implanted device, and others use an external pacemaker that wirelessly stimulates an electrode implanted in the heart.Another possibility is to scavenge energy from the natural processes occurring in the patient's body.
In this case, a biologist, robotics engineer and analog-chip designer collaborated on a walking robot that used the principle of a "central pattern generator" (CPG a kind of flexible pacemaker that humans and other animals use for locomotion.
This means no coaches shouting instructions from the sidelines and no sacrificial pacemaker easing the way ahead, as is common in cycling or distance running.
"What are the top ten signs that your pacemaker is running Windows?" he once asked.
Smaller than a battery and reusable, it holds enough charge to keep the pacemaker running for an hour, buying doctors time to try and revive the patient.
