1. Garment

  • Worn under your normal clothing, directly against skin
  • Includes the electrode belt

2. Electrode Belt

  • Designed to detect dangerous heart rhythms and deliver a treatment shock

3. Monitor

  • Worn around waist or with shoulder strap
  • Continuously records heart rate

The LifeVest® wearable cardioverter defibrillator (WCD) allows you to return to most of your normal daily activities with the peace of mind that you have protection from sudden cardiac death. LifeVest does not require the assistance of another person or emergency personnel for it to work. It can protect you even when you are alone.

LifeVest is designed to detect a life-threatening rapid heart rhythm and automatically deliver a treatment shock to restore your normal rhythm. The entire event, from detecting a life-threatening rapid heartbeat to automatically delivering a shock, usually takes less than a minute.

LifeVest does not treat all heart conditions, such as a dangerously slow heart rate or a complete stoppage of the heart, which are not treatable by a defibrillation shock.
