The FDA has recently approved the LifeVest Wearable Cardioverter Defibrillator to be marketed. The Zoll LifeVest is a wearable cardioverter defibrillator to monitor and treat dangerous, abnormally fast heart rhythms. These abnormal rhythms can lead to a complete absence of heartbeat (sudden cardiac arrest) and death (sudden cardiac death) if they are not treated. This device was first approved for patients 18 years of age and over in 2001, and it is now available for children.
The LifeVest is worn outside the body day and night. It treats abnormal rhythms by applying a high energy shock similar to that of a traditional defibrillator.
