An implantable cardioverter defibrillator (ICD) surgery is a procedure to implant a device inside the body, able to prevent sudden death from cardiac arrest due to life threatening abnormally fast heart rhythms or fibrillation.

2 to 3 Hours
An ICD is a device with battery that goes under the skin and somehow control the heart rate. Thin wires connect the ICD to heart. If an abnormal heart rhythm happen, the device will give an electric shock to heart to restore a normal heartbeat. ICDs have been very useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown that, they may have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias.
Before making the decision for placing an ICD, some information about heart is required such as: • Heart rhythm pattern by electrocardiogram (EKG) • Heart rhythms for a 24-hour period (during regular activities) by Holter monitoring • Heart activity and oxygen saturation during either rest or exercise. Patients should tell a complete medical history to the doctor. Also need to let the doctor know about all of the medicines and supplements (vitamins, minerals and herbal medicines) taken and allergies. Doctor will manage patient’s medicines because some medicines like warfarin, aspirin and Plavix should be stopped some days prior to the surgery.
