The Science Behind It
How It Works
The first variation is called the Automated External Defibrillator. The AED is commonly found in work places or public buildings. The AED is small and portable and can be operated by anybody that can listen to instructions.The AED contains a small computer that will analyze the victims heart beat when the two sticky pads are applied to the chest. The AED will then prompt the operator to deliver the shock via a button press. The use of an AED in resuscitating a unconscious non-breathing victim greatly increases their chance of surviving.
The second variation is the Internal Cardioverter Defibrillator which is a small implantable computer that monitors your heart rhythm. If the computer detects an irregular heart beat then a small charge will be sent to your heart to correct the rhythm. If the heart does not revert back to normal a stronger charge will be sent and can be painful. Having an ICD reduces the risks of having a heart failure but comes with a different set of risks all together. A few risks are an unwanted electrical shock or damage to nerves, blood vessels, and your heart. The longer you have an ICD the greater the risks become.
