Implantable Cardioverter Defibrillator (ICD) Implantation

An implantable cardioverter defibrillator (ICD) is a small battery-powered device placed in your chest to constantly monitor your heart rhythm and immediately deliver electric shocks when life-threatening arrhythmia is discovered, usually when the lower left chamber of the heart beats abnormally fast. The implantable cardioverter defibrillator (ICD) helps normalize heart rhythm. This type of arrhythmia can lead to death due to heart attack. The implantable cardioverter defibrillator (ICD) can also stimulate the heart when it beats too slowly.

The Implantable Cardioverter Defibrillator (ICD) Components

1.    A pulse generator, which is a tiny computer powered by battery.

2.    One or two leads, wires that deliver electrical signals between the pulse generator and the heart.

3.    Electrodes at the ends of the leads, to help deliver the signals when the device detects abnormal heart rhythms. The generator will send electrical signals to the heart to return to normal rhythm.

  1. Bleeding or hematoma, and infection where the implantable cardioverter defibrillator (ICD) was implanted.
  2. Allergic reaction to the medications used during the procedure.
  3. Damage to blood vessels.
  4. Bleeding in the pericardium.
  5. The implantable cardioverter defibrillator (ICD) sends abnormal signals to the heart or malfunctions or the leads come loose.
  6. Stroke, heart attack, or other serious complications, which are uncommon.
  7. Death (rare).
Let your doctor know if you develop problems, such as:
  1. Bleeding, swelling or increased pain at the implantation site
  2. Fever
  3. Dizziness
  4. Fainting
  5. Chest pain
  6. Difficulty breathing
