Restless legs syndrome, also known as Willis-Ekbom disease, is a common condition of the nervous system that causes an overwhelming, irresistible urge to move the legs. It can also cause an unpleasant crawling or creeping sensation in the feet, calves and thighs.
Defibrillation is a technique used in emergency medicine to terminate ventricular fibrillation or pulseless ventricular tachycardia. It uses an electrical shock to reset the electrical state of the heart so that it may beat to a rhythm controlled by its own natural pacemaker cells.
The human heart is a delicate muscle and must be taken care of. Sometimes disease can cause malfunction to occur and the heart to stop beating. When this happens, it is necessary to resuscitate the person to bring him/her back to life. This is done by sending electric shocks to the heart muscle until it starts beating again. This shock is administered by a device called a defibrillator. These defibrillators range in the amount of shocks they can administer. From the discrepancies in the research, there does not seem to be an universal amount that will revive a heart.
