The more I look at modern technological breakthroughs, the more I am in awe. These days, we actually have devices that are able to detect if your heart is about to fail, and then take steps to prevent a heart attack. I am referring to a device called an ICD, or implantable cardioverter-defibrillator. This device is a battery run electrical pulse emitter that is connected to a patient's heart with very tiny wires and includes a component that monitors heart rate. If a patient's heart rate becomes erratic, the ICD can deliver a shock that will set the heart back into a normal rhythm. Such devices are generally recommended by doctors to patients who have had heart attacks in the past or other serious heart issues.
