What is an ICD?
An Implantable Cardioverter Defibrillator (ICD) is a small device placed under the skin (usually below the collarbone) that continuously monitors heart rhythm. If it detects a dangerous rhythm, it can deliver pacing or a life-saving shock to restore a safer rhythm.
Who may need ICD implantation?
Your cardiologist may recommend ICD implantation for people at higher risk of life‑threatening ventricular arrhythmias or sudden cardiac arrest. The decision is individualized and based on symptoms, heart function, prior events, and guideline-based risk assessment.
Inside the cath lab: how the ICD procedure is typically performed
ICD implantation is usually performed in a sterile cath lab / electrophysiology environment with continuous monitoring. While exact steps vary by patient and device type, the procedure commonly includes:
Pre‑procedure evaluation and consent, including review of ECG, echocardiography and other relevant tests.
Local anesthesia with sedation (or anesthesia when clinically required).
A small incision below the collarbone and creation of a pocket for the device.
Placement of one or more leads through a vein into the heart under imaging guidance.
Testing of lead position and electrical parameters to ensure reliable sensing and therapy delivery.
Connection of leads to the ICD generator, placement in the pocket, and layered closure.
Post‑procedure monitoring and device programming tailored to the patient’s rhythm profile.
Safety, sterility and monitoring in a modern cath lab setup
A modern cath lab setup supports precision and safety through imaging guidance, strict infection-control protocols, and continuous monitoring of heart rhythm, oxygen levels and blood pressure. At Shreejii Hospital & Research Center, our teams follow standardized safety checklists and evidence-based protocols to support consistent outcomes.
Recovery after ICD implantation
Most patients can resume light daily activities soon after discharge, with specific precautions for arm movement on the implant side for a short period. Your cardiologist will advise on wound care, medications, follow-up device checks, and when you can return to work, driving, and exercise.
When to seek urgent help
Seek urgent medical attention if you develop chest pain, breathlessness, fainting, fever, increasing redness/swelling at the wound, or if you receive repeated shocks. Always follow your treating doctor’s instructions.

FAQs
Is ICD implantation a major surgery? ICD implantation is typically a minimally invasive procedure performed in a cath lab/EP setting, but it is still a significant medical procedure and requires expert evaluation.
How long does an ICD last? Battery life varies by device and how often therapy is delivered; your cardiologist will monitor it during follow-ups.
Will I feel an ICD shock? Some people feel a shock if delivered; many therapies are painless pacing. Your device is programmed to minimize unnecessary shocks.
Can I undergo MRI after ICD implantation? Some devices are MRI-conditional. Always confirm with your cardiologist and carry your device card.
How often are follow-ups needed? Regular device checks are important; the schedule is individualized.
