What Is the LifeVest Wearable Defibrillator?

The LifeVest® wearable cardioverter defibrillator (WCD) is a treatment option for patients at risk of sudden cardiac death (SCD) that offers advanced protection and monitoring as well as improved quality of life.

LifeVest is a wearable defibrillator. Unlike an implantable cardioverter defibrillator (ICD), LifeVest is worn outside the body rather than implanted in the chest. LifeVest is designed to continuously monitor a patient’s heart, detect life-threatening rapid heart rhythms, and automatically deliver a treatment shock to restore normal heart rhythm.

The device alerts a patient prior to delivering a treatment shock, and thus allows a conscious patient to delay the treatment. If the patient becomes unconscious, the device is designed to release a Blue™ gel over the therapy electrodes and deliver an electrical shock to restore normal rhythm.
