A cardiac life vest is an emergency device that detects a rapid heart rhythm and automatically delivers a shock to restore a normal heartbeat. The entire process, from detecting a rapid heartbeat to delivering the shock, usually takes less than a minute.
The device can be used by anyone with a reduced left ventricular ejection fraction (how well the heart pumps blood). Patients also may be given one to use while they are waiting for an implantable cardioverter defibrillator, or ICD, to be inserted.
Defibrillator
The defibrillator used in cardiac life vests for adults is a small, lightweight device that can quickly and effectively control dangerously fast heart rhythms. It can restore a normal heart rhythm in minutes, boosting a patient’s chance of survival.
A defibrillator works by sending electrical shocks to the heart. This shock can cause pain or even death if it’s applied too soon, but it’s one of the best treatments for sudden cardiac arrest.
Defibrillators are often used in combination with cardiopulmonary resuscitation (CPR) to help keep a person alive after he or she experiences cardiac arrest. CPR keeps blood flowing to the heart and brain for a while, but often only defibrillation can restore a normal heart rhythm and improve a patient’s chances of survival.
Defibrillators can be used by anyone, as long as they know how to use them correctly and don’t inadvertently shock someone who doesn’t need it. They are also easy to operate, generating pre-recorded voice instructions and automatically checking the user’s condition and applying the correct electric shocks.
Monitor
If a life-threatening rapid heart rhythm starts, the monitor will automatically deliver a treatment shock. This will prevent sudden cardiac arrest and restore normal heart rhythm.
Cardiac life vests are designed for people who are at risk of developing ventricular arrhythmias that may lead to sudden cardiac arrest. These include those with reduced heart function following a heart attack, those who are waiting to see if their low ejection fraction will go away with medication, and patients with heart failure or cardiomyopathy.
The vest and electrode belt are worn underneath clothes all day (except for showers or baths). Electrodes inside the device pick up your electrocardiogram (EKG).
If a life-threatening heart rhythm is detected, the monitor will activate the defibrillator and deliver one or more treatment shocks. This restores the heart’s normal rhythm and saves a person’s life.
Batteries
A cardiac life vest for adults is a bit more expensive than your average heart attack treatment, but it does offer you a measure of protection from the sudden demise of your heart. It consists of a light-weight fabric tuxedo that is tucked under your shirt, paired with a monitor that is small enough to fit in the palm of your hand and a battery. It is also the most important thing you can do to protect yourself from a potentially fatal heart attack. For better or worse, you will likely be wearing it for the rest of your life.
Instructions
A cardiac life vest for adults is a type of personal defibrillator that is worn under your clothing 24 hours a day. It helps you prevent sudden cardiac arrest (SCA), which can be fatal if left untreated.
The main part of the LifeVest is a lightweight garment that you wear under your clothes directly against your skin. This garment contains electrodes that pick up your electrocardiogram (ECG), or heart rhythm, and a defibrillator pad that delivers shocks to restore a normal rhythm. The LifeVest monitor is worn around your waist or from a shoulder strap, and it can alert you when you have a life-threatening heart rhythm.
Medicare will cover the cost of this device if you have a high risk of sudden cardiac arrest or are recovering from a heart attack and have reduced left ventricular ejection fraction. Your cardiologist will determine whether or not you qualify for this treatment. Your doctor will also help you learn how to use the life vest and understand what alarms are on your device.
