An Implantable Cardioverter-Defibrillator (ICD) is a life-saving device designed to monitor and treat life-threatening heart rhythm disorders, particularly ventricular tachycardia and ventricular fibrillation. By delivering electrical shocks when necessary, an ICD can restore a normal heartbeat and prevent sudden cardiac arrest.
With over 15 years of experience and more than 1,000 device implants, Dr. PavanKumar P Rasalkar is a trusted expert in ICD implantation, offering advanced care tailored to each patient’s needs.
An ICD may be recommended if you have:
A history of sudden cardiac arrest or ventricular fibrillation
Severe heart failure with a reduced ejection fraction (≤35%)
Inherited arrhythmia syndromes (e.g., Long QT Syndrome, Brugada Syndrome)
Previous heart attack with compromised heart function
Non-ischemic cardiomyopathy with recurrent life-threatening arrhythmias
Transvenous ICD
Implanted under the skin near the collarbone
Leads are threaded through veins into the heart
Suitable for most patients requiring defibrillation
Subcutaneous ICD (S-ICD)
Placed just under the skin, avoiding contact with the heart
Ideal for patients at risk of infection or those with limited vascular access
Does not provide pacing capabilities
Preparation:
Performed under local anesthesia with sedation
Small incision made near the collarbone
Device Placement:
Leads are inserted through a vein and positioned in the heart
Pulse generator is placed under the skin
Testing:
Device functionality is tested to ensure proper operation
Recovery:
Typically requires a 1-day hospital stay
Full recovery may take 4–6 weeks
Prevents sudden cardiac arrest
Monitors heart rhythms continuously
Delivers shocks to restore normal rhythm when necessary
Improves survival rates in high-risk patients
Enhances quality of life by reducing anxiety related to arrhythmic events
Over 1,000 device implants performed
Expertise in both transvenous and subcutaneous ICDs
Utilizes advanced imaging for precise lead placement
Provides comprehensive follow-up care, including remote monitoring
Practices at Unique Healthcare Centre – Rajajinagar & Banashankari, Bangalore
Patients with an ICD can lead active lives with some precautions:
Avoid strong magnetic fields (e.g., MRI machines, certain electrical equipment)
Inform all healthcare providers about your ICD
Regular check-ups to monitor device function
Lifestyle adjustments may be recommended based on individual health status
If you’re at risk of life-threatening arrhythmias, an ICD can be a critical component of your treatment plan.
