A wearable defibrillator that automatically responds to arrhythmia has received FDA approval for certain children who are at risk of sudden cardiac arrest. This device was first approved for adults in 2001.
The LifeVest, manufactured by ZOLL Medical Corporation in Pittsburgh, Pennsylvania, is a lightweight garment with an electrode belt that fits just below the chest. The belt extends from a section that covers the upper back and has straps that fit over the shoulders.
