The LifeVest Wearable Defibrillator

The LifeVest wearable defibrillator is a personal device used to detect life-threatening arrhythmias and provide a shock to restore a normal heartbeat. It is safe, easy to use, and lightweight.

It is worn by patients who are at risk for sudden cardiac arrest, like those who have just had a heart attack or are waiting for a defibrillator implant. It gives a doctor time to assess the patient’s long-term arrhythmic risk and make appropriate plans.

How it works

A lifevest wearable defibrillator monitors your heart all the time and delivers a shock when it detects a dangerous arrhythmia. The shock restores your heart rhythm back to normal.

The device consists of a vest, electrode belt, and a monitor that can be worn around your waist (like a fanny pack) or over a shoulder strap. The electrodes, which are made of a lightweight fabric, rest against your skin and pick up your electrocardiogram (EKG).

If a life-threatening heart rhythm is detected, LifeVest delivers a treatment shock to restore a normal rhythm within one minute. The surprise is delivered through three electrodes in the garment electrodes placed on the vest’s front and back.

The wearable defibrillator is designed to reduce the risk of sudden cardiac death in people with reduced left ventricular ejection fraction who have had a heart attack. It can also help protect people who are waiting for an implantable cardioverter defibrillator or who have a history of heart failure.

How to use

A lifevest wearable defibrillator is a device that people can wear if they’re at risk for sudden cardiac arrest. It monitors a person’s heart continuously, detects life-threatening arrhythmias such as ventricular tachycardia and ventricular fibrillation, and delivers treatment shocks to restore a normal rhythm.

The device consists of a vest and an electrode belt worn under clothing, directly against the skin. It contains therapy pads and ECG electrodes that continuously monitor a person’s heart rhythm.

It also includes a vibration box that notifies a person when a lethal arrhythmia is detected. The device can send an alarm to bystanders so they can help the patient if needed.

The LifeVest wearable defibrillator is an alternative to an implantable cardioverter defibrillator (ICD) if your doctor decides you’re at a higher risk of sudden cardiac death. It provides a temporary safety net until you’re able to qualify for an ICD.

Getting started

If you’re at risk for sudden cardiac arrest, your doctor may recommend a lifevest wearable defibrillator. This device monitors your heart rhythm all the time and delivers a shock if it detects certain life-threatening rapid heart rhythms.

Unlike standard automated external defibrillators (AEDs), the lifevest wearable defibrillator is worn directly against your skin and does not require another person to be nearby. This provides you with a constant safeguard against sudden cardiac death so that you can get back to your daily activities.

This type of wearable defibrillator is used as an intermediate-term treatment option for people at high risk of sudden cardiac arrest. It fills the gap between being monitored in an ICU or CCU and getting an implantable cardioverter defibrillator (ICD).

The lifevest wearable defibrillator consists of a garment that is lightweight and can be worn under clothes, along with an electrode belt. The belt has therapy pads that generate an electric shock when a rhythm is detected and ECG electrodes that continuously monitor the rhythm. It also has a vibration box that notifies the patient if they are about to receive a shock.


A lifevest wearable defibrillator is an effective tool for patients with cardiomyopathy or congestive heart failure who are at a high risk of sudden cardiac arrest. The device can also be helpful for patients with low left ventricular ejection fraction (LVEF) who may be waiting to see if medications will help improve their condition or expect to have heart surgery.

The LifeVest is a lightweight device consisting of a chest garment and elastic belt with a connected monitor and defibrillator unit. A battery-operated monitor detects dangerous irregularities in a person’s heart rhythm and triggers the LifeVest defibrillator when an arrhythmia is detected.

The device has multiple alerts, including a gong alert, a vibration alarm, two siren tones, and a warning voice. It can be used by lay rescuers or professionals in emergency and critical care. The device is accompanied by a software package to enhance patient safety and efficiency while reducing resuscitation time and costs.
