The LifeVest® wearable cardioverter defibrillator (WCD) is designed to protect patients at risk of sudden cardiac death (SCD), when a patient’s condition is changing and permanent SCD risk has not been established. This allows a patient’s doctor time to assess the patient’s long-term arrhythmic risk and make appropriate plans.

LifeVest is lightweight and easy to wear, allowing patients to return to most of their daily activities, while having the peace of mind that they have protection from SCD.¹ LifeVest is designed to continuously monitor a patient’s heart, detect certain life-threatening rapid heart rhythms, and automatically deliver a treatment shock to restore normal heart rhythm.

LifeVest has been worn by more than one million patients at risk of sudden cardiac death.² It is the most used, studied, and proven wearable defibrillator.^3,4

LifeVest is designed to detect certain life-threatening rapid heart rhythms and, if needed, automatically deliver a treatment shock to restore normal heart rhythm. Timely defibrillation is the single most important factor to save a patient that is experiencing a rapid, life-threatening arrhythmia. A treatment shock must be delivered within a few minutes after an event to be effective; with each passing minute, a patient’s chances of survival drops 10 percent. LifeVest does not require bystander intervention. In a typical situation, the entire event, from detecting a life-threatening rapid heartbeat to automatically delivering a shock, occurs in about one minute.

LifeVest is made of lightweight fabric and is easy to wear, allowing patients to return to most common activities of daily life like work, shopping and moderate exercise, while having peace of mind that they have protection from SCD.

The LifeVest WCD is fit to a patient’s body and is worn under regular clothes. Other than the monitor, which is worn in a holster around the waist or on a shoulder strap, there is no evidence that a person is wearing the device.

Patients should wear the LifeVest WCD at all times, including while sleeping. LifeVest should only be removed when a patient is showering or bathing.

Use of an AED requires bystander assistance. The bystander operates the AED by applying the electrodes to the patient and following instructions.

By contrast, the LifeVest WCD requires no bystander intervention. LifeVest can protect patients when they are alone or sleeping. LifeVest is designed to continuously monitor a patient’s heart, detect certain life-threatening rapid heart rhythms, and automatically deliver a treatment shock to restore normal heart rhythm. In addition, LifeVest can offer peace of mind for family members who may worry about awaiting EMS personnel arrival or having to resuscitate a loved one themselves.

LifeVest is available in the United States, Europe, Japan, and several other countries worldwide.
