The LifeVest® wearable cardioverter defibrillator protects individuals at risk of sudden cardiac death (SCD). While some defibrillator devices are implanted under the skin, the LifeVest® is worn directly against the patient’s skin. It is lightweight and easy to wear, allowing the individual to return to most of their daily activities with peace of mind that they have protection. LifeVest is designed to detect a life-threatening rapid heart rhythm and automatically deliver a treatment shock to save a patient’s life.
