The body generates electrical impulses that cause the heart to beat. In some people, those electrical impulses don't happen in a normal pattern, which can cause the heart to beat too slowly, too fast or irregularly. A very fast heartbeat can lead to ventricular tachycardia, a potentially life-threatening condition. In patients who are at risk for ventricular tachycardia, doctors often recommend an implantable cardioverter defibrillator or ICD.
Atrial fibrillation causes the heart to beat out of rhythm. To get the heart beating normally again, sometimes the heart is 'shocked' into normal rhythm. The idea of shocking the heart may be intimidating, but it's actually a quick and painless procedure.
When diagnosed with atrial fibrillation, the first line treatment that cardiologists typically recommend is medications. However, over time the medications may no longer be effective or may not provide symptom relief. In these cases your health care provider may recommend a heart procedure known as catheter ablation.
The procedure for implanting an ICD is often routine and relatively easy for the patient. The health care team will tell the patient how to prepare for surgery and what to expect during the procedure.
