VIDEO - The wearable defibrillator

In a cardiac emergency, a defibrillator can be a lifesaver. "It senses if the heart stops and can actually shock the heart internally and return normal function," says Dr. Richard Chazal, a cardiologist with Lee Memorial Health System. Most people are familiar with AEDs or Automatic External Defibrillators, the devices that you see in public places like malls and stadiums. But, a new option is the wearable defibrillator, which can be worn by people at high risk for a cardiac event, usually while they wait for surgery or other more advanced treatment.
