Implantable Cardioverter Defibrillator (ICD) in Pimpri Chinchwad, Pune India

Introduction to Implantable Cardioverter Defibrillator (ICD)

What is an ICD?

An ICD (Implantable Cardioverter Defibrillator) is a small, battery-powered device placed under the skin to monitor heart rhythm and deliver electric shocks if a life-threatening arrhythmia is detected.

Importance of ICD in Preventing Sudden Cardiac Arrest

ICDs are critical in preventing sudden cardiac arrest (SCA), particularly in patients with a history of ventricular arrhythmias or weakened heart muscles.

How an ICD Works

The device continuously monitors heart rhythms. If it detects an abnormal pattern like ventricular tachycardia or fibrillation, it sends electrical pulses or shocks to restore a normal rhythm.

Who Needs an ICD?

• Conditions Requiring an ICD:
• Ventricular arrhythmias
• History of sudden cardiac arrest
• Heart failure with low ejection fraction (EF ≤ 35%)
• Inherited arrhythmia syndromes (e.g., Long QT syndrome)
• Risk Factors:
• Previous heart attack
• Family history of cardiac arrest
• Cardiomyopathy or myocarditis
• Episodes of fainting with known heart disease

Types of ICD Devices

1. Single-Chamber ICD: Connected to one chamber (usually the right ventricle).
2. Dual-Chamber ICD: Connected to both right atrium and right ventricle.
3. Biventricular ICD (CRT-D): Used in patients with heart failure to improve synchronization of the heart's ventricles.

ICD vs. Pacemaker

While both are implantable devices, pacemakers regulate slow heart rhythms, whereas ICDs treat fast, dangerous arrhythmias.

ICD Implantation Procedure

• Step-by-Step Process:
• Pre-surgery tests and imaging
• Local or general anesthesia administration
• Insertion of leads via vein into the heart
• Device placed under skin near the collarbone
• Testing and closure

Duration: Typically 1–2 hours

• Before, During & After Surgery:
• Fasting before procedure
• Mild discomfort after implantation
• Overnight hospital stay in most cases

Life After ICD Implantation

• Recovery Process:
• Most patients resume light activities in a few days, with complete recovery in 4–6 weeks.
• Follow-Up:
• Regular check-ups and device interrogation every 3–6 months.
• Activity Restrictions:
• No strenuous upper-body movements for a few weeks
• Avoid heavy lifting initially
• Return to Routine:
• Gradual return to work and driving (based on cardiologist's advice)

Risks and Complications of ICD Implantation

• Possible complications: infection, lead dislodgement, inappropriate shocks

How Aditya Birla Hospital minimizes these risks with experienced electrophysiologists and advanced care

ICD Battery Life and Replacement

• Battery Life: Typically 5–10 years depending on usage
• Monitoring: Device alerts when replacement is due
• Replacement: Minimally invasive, typically day-care procedure

Living with an ICD

• Lifestyle Considerations:
• Travel: Allowed; carry ICD identification card
• Driving: Temporarily restricted post-implantation
• Mobile Phones & Appliances: Safe with basic precautions (keep phones >6 inches from device)
• EMI Caution: Avoid strong magnetic fields (e.g., MRI unless device-compatible)
