ICD Implantation
What Is ICD Implantation?
ICD implantation is a procedure in which an implantable cardioverter-defibrillator (ICD) is placed under the skin, usually in the chest, to continuously monitor heart rhythm and treat potentially dangerous abnormal heartbeats. The device can deliver electrical pulses or a shock when it detects a life-threatening rhythm such as ventricular tachycardia or ventricular fibrillation.
Who May Need an ICD?
An implantable cardioverter-defibrillator may be recommended for people who have survived cardiac arrest, experienced certain dangerous ventricular arrhythmias, or have a high risk of sudden cardiac death because of specific heart conditions or reduced heart function. The decision depends on the individual's heart condition, test results, medical history, and overall health.
How Is ICD Implantation Performed?
Before the procedure, the cardiology team may perform tests such as an ECG and echocardiogram to assess heart rhythm and function. During implantation, the device is positioned beneath the skin and, in a traditional ICD, leads are guided through a blood vessel to the heart. The ICD is then programmed according to the patient's clinical needs.
Recovery and Follow-Up
Patients may experience temporary tenderness or swelling around the implant site. Follow-up appointments are important for checking the device, leads, and battery and for adjusting settings when necessary. Patients should follow their cardiologist's instructions regarding physical activity, driving, and other daily activities during recovery.
