LifeVest Patient FAQs

Q: What is the LifeVest wearable cardioverter defibrillator (WCD)?

A: The LifeVest® wearable cardioverter defibrillator (WCD) is worn by patients at risk of sudden cardiac death (SCD). A defibrillator is a device that is used to control dangerously fast heart rhythms by applying an electrical shock to the heart. While some defibrillator devices are implanted under the skin, the LifeVest WCD is worn directly against the patient’s skin. With LifeVest, patients can have a constant safeguard against SCD.

Q: What is sudden cardiac death?

A: The heart’s electrical system controls the heartbeat. When this system fails, it may trigger a dangerously fast heartbeat. This fast heartbeat causes the heart to quiver or shake instead of pumping blood to the body and brain. When this happens, you can suddenly pass out. This is sudden cardiac arrest (SCA). It occurs without warning. Without treatment, death occurs in minutes. This is sudden cardiac death (SCD).

With LifeVest, patients can have a constant safeguard against SCD. LifeVest is designed to detect certain life-threatening rapid heart rhythms and automatically deliver a treatment shock to restore your normal rhythm. Visit the What is Sudden Cardiac Death? page to learn more.

Q: Why do I need the LifeVest WCD?

A: Your doctor believes that your current condition puts you at risk for developing certain life-threatening rapid heart rhythms, which can occur at any time and without warning. This could cause you to become unconscious and unable to call for help. Your doctor prescribed LifeVest for protection from sudden cardiac death so that you can continue to be there for your family. The risk of SCD is high for certain heart patients. You may be at a higher risk for SCD if you have or experience one of the following:

  • A low ejection fraction (EF) or weak heart muscle
  • Prior heart attack
  • Heart failure
  • A history of sudden cardiac death in your family
  • A viral infection in your heart
  • Other risk factors for SCD include high blood pressure, diabetes, obesity, smoking, and high cholesterol.

No matter your condition, it is important to remember that the LifeVest WCD can provide a constant safeguard against SCD. With LifeVest, you and your loved ones can have peace of mind knowing that you can have protection.7

Q: How does LifeVest work?

A: LifeVest consists of a garment, an electrode belt, and a monitor. When you wear the LifeVest WCD directly against your skin, the device can continuously monitor your heart. If you experience certain life-threatening rapid heart rhythms, the LifeVest WCD is designed to shock your heart back into a normal rhythm. In a typical situation, the entire event, from detecting a life-threatening rapid heartbeat to automatically delivering a shock, occurs in about one minute. Visit the How Does LifeVest Work? page to learn more and view pictures of the LifeVest WCD.

Q: What do the alerts mean?

A: One of the key features of LifeVest is the series of alerts and voice prompts that keep you informed about what the device is doing. These alerts let you know that LifeVest is working to protect you.

Loud or high vibration environments can make it difficult for you to hear an alert, so if you find yourself in these types of environments or situations, you should be extra attentive to the LifeVest WCD to ensure that you are able to respond to any alerts. For example, riding a motorcycle or using some lawn mowers may cause vibration and make it difficult for you to hear an alert, which may result in an inappropriate treatment. To learn more, visit the Living with LifeVest page.

Q: What should I do if I hear an alert or alarm?

A: While wearing LifeVest, you may get an alert. It is very important for you to know what the alert means and how to respond. Remember, these alerts are part of the normal functioning of the device and let you know that it’s working to protect you. If you get an alert, you should take action quickly. Remember, no one else should hold the response buttons. Only the patient should hold the response buttons.

Q: What should I do if there is BlueTM gel on me?

A: LifeVest is designed to release BlueTM gel on your chest and back prior to delivering a treatment.
