Implantable cardioverter defibrillators (ICDs) are commonly used in patients with
heart failure. About half of those with heart failure might benefit from an ICD to help prevent sudden cardiac death. An ICD can be especially helpful in
people with reduced ejection fraction (when the heart doesn’t squeeze as well as it should).
If you have heart failure and are considering an ICD, use this booklet to learn about the device and why your doctor is recommending one. It will help you gather information to be able to make a decision to have an ICD placed or not, based on your values and wishes.
