Automatic Cardioverter Defibrillator Implantation
(Implantable Cardioverter Defibrillators [ICD]; Automatic Implantable Cardioverter Defibrillator [AICD])

Reasons for Procedure
- Bradycardia—heart beating too slowly
- Ventricular tachycardia—heart beating too rapidly
- Ventricular fibrillation—heart muscle not pumping, but just quivering
- Have had one or more episodes of serious irregular heart rhythms
- Have had a heart attack and are at high risk for arrhythmias
- Have a high risk of dangerous arrhythmias
- Have a weakened heart muscle
- Have a high likelihood of developing an arrhythmia
- Have the condition known as hypertrophic cardiomyopathy, which is an enlarged heart muscle that does not function properly
- Damage to the heart or lungs
- Damage to blood vessels
- Inappropriate shocks or device malfunction
What to Expect
Prior to Procedure
- Blood tests
- Chest x-ray—a test that uses radiation to take a picture of structures inside the body
- Electrocardiogram (ECG), implantable loop recorders (ILR), electrophysiology study (EPS)—tests that record the heart’s activity by measuring electrical currents through the heart muscle
- Echocardiogram—ultrasound to evaluate heart structure and function
- Stress testing or cardiac catheterization—to evaluate for coronary artery disease
- Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
- The night before, eat a light meal. Do not eat or drink anything after midnight.
- Ask your doctor if you should take your daily medications with a sip of water on the day of the procedure.

Average Hospital Stay
You may need to avoid:
- MRI scans
- Heat therapy, which is often used in physical therapy
- High-voltage or radar machinery, such as electric arc welders, high-tension wires, radar installations, or smelting furnaces
- Contact with radio or television transmitters
- Prolonged contact with household appliances, such as microwave ovens
- Do not carry a cell phone in a pocket directly over the device. Keep your phone on the side away from the device. Also, headphones worn with MP3 players may cause interference.
- Turn off car or boat motors when working on them. They may temporarily confuse your device.
- Tell your doctor or dentist that you have a device before a surgical procedure.
- Check with your doctor about the safety of going through airport security detectors with your particular device. Do not linger in security devices.
- Be sure to follow your doctor’s instructions.
Call Your Doctor
- You feel a shock
- Signs of infection, including fever and chills
- Redness, swelling, increasing pain, excessive bleeding, or discharge from the incision site
- Pain that you cannot control with the medicines you have been given
- Cough or severe nausea or vomiting
- Have chest pain or shortness of breath
- Feel lightheaded and do not feel a shock
- You are still feeling symptoms after a shock
- You feel 3 or more shocks in a row
