If your rhythm problem is a fast or irregular heartbeat in which not enough or no blood is pumped to your body (ventricular tachycardia or ventricular fibrillation) you may need an implantable cardioverter defibrillator (ICD) placed.
This type of rhythm problem causes fainting spells or cardiac arrest, and can be life threatening. An ICD will shock your heart back to a normal rhythm, many times before you even notice symptoms, or pace your heart if your heart rate becomes too slow. The ICD is both a generator to deliver the electrical shock and a computer that records the heart rhythm and the shocks that are needed.
The doctor (electrophysiologist) will review all of your previous tests, which may include ECG’s, heart catheterization, stress tests, Holter monitors, and electrophysiology studies to determine if you are a candidate for an ICD. If he/she determines that you need an ICD, you will have the device implanted in the hospital.
During the procedure, a local anesthetic will be given in the area of your collarbone to numb the site (You will be given IV medication to relax you during the procedure). An incision is then made for the ICD generator and lead wires. The doctor will test the generator and the lead wires to ensure proper function of the device. After the procedure, a dressing will be applied to the area.
You will need to keep the arm on that side of your body immobile for several days after the procedure so that the lead wire is not displaced. You may need to wear a sling to remind you to keep the arm still. Your physician will let you know when to return for follow up appointments, and when you can return to work.
