AICD (Automatic Implantable Cardioverter Defibrillator) in Mumbai
Life-Saving Therapy for Dangerous Heart Rhythms
Consult Dr. Siddharth Sheth – Best Interventional Cardiologist in Mumbai
Understanding Life-Threatening Arrhythmias
An AICD (Automatic Implantable Cardioverter Defibrillator) is a specialized device implanted in patients at risk of sudden cardiac arrest due to dangerous ventricular arrhythmias - abnormal heartbeats that occur in the lower chambers of the heart, and can cause the heart to beat too fast, too slow, or irregularly.
Unlike a standard pacemaker, an AICD can deliver an electric shock to restore normal heart rhythm during a life-threatening event. It's like having a 24/7 emergency response team inside your chest.
AICD Implantation is Recommended For:
- Severe heart failure with reduced pumping capacity
- History of ventricular tachycardia or ventricular fibrillation
- Survivors of previous sudden cardiac arrest
- High risk of sudden cardiac death identified through testing
- Certain genetic conditions (Long QT syndrome, Brugada syndrome, hypertrophic cardiomyopathy)
What Is AICD Implantation?
AICD implantation is a minimally invasive procedure performed under local anesthesia with sedation.
The Procedure:
- A small incision is made in the chest, typically under the collarbone
- Thin, flexible wires called leads are guided through a vein and positioned inside the heart
- The leads are connected to the AICD device
- The device is thoroughly tested to ensure it can detect and treat abnormal rhythms
- The AICD continuously monitors heart rhythm and corrects abnormal rhythms automatically
- The AICD is placed in a small pocket under the skin and programmed for your specific needs
Hospital Stay:
Most patients are discharged in 1–2 days, with instructions for monitoring and device care.
Why AICD Is Different from a Pacemaker
| Feature | Pacemaker | AICD |
|---|---|---|
| Primary function | Treats slow heart rates | Stops dangerous fast rhythms |
| Can deliver shock | No | Yes |
| Patient profile | Bradycardia, heart block | High risk of sudden cardiac arrest |
| Device size | Smaller | Slightly larger |
- Protects against sudden cardiac arrest – the ultimate safety net
- Continuously monitors heart rhythm and corrects life-threatening arrhythmias automatically
- Improves survival in high-risk heart patients by 30–50%
- Provides peace of mind and reduces anxiety for patients and families
- Allows many patients to return to normal activities and quality of life
- Remote monitoring capabilities for added convenience and safety
An AICD functions as your personal cardiac emergency response system. If a dangerous rhythm occurs, the device acts immediately - often before you even lose consciousness.
However, if you experience:
- Multiple shocks in a short period
- Shocks accompanied by chest pain or dizziness
- Feeling unwell after a shock

Heart Attack Treatment Mumbai: The AICD Connection
Patients who have undergone heart attack treatment often develop weakened heart muscle, putting them at higher risk for dangerous arrhythmias. An AICD may be recommended as part of comprehensive post-heart attack care if:
- Ejection fraction remains below 35% despite optimal medication
- Ventricular arrhythmias occur after the heart attack
- Sudden cardiac death risk is deemed high
Dr. Sheth specializes in identifying patients who will benefit most from this life-saving therapy.
AICD implantation is generally very safe, especially in experienced hands. Potential risks (rare) include:
- Bleeding or Infection at the device site
- Lead displacement (requiring repositioning)
- Inappropriate shocks (rare)
- Device malfunction(rare)
Dr. Sheth has extensive experience in safe AICD implantation for adults and elderly patients, minimizing these risks significantly.
First Week:
- Keep incision dry for 5–7 days
- Avoid lifting heavy objects
- Gentle walking encouraged
- No driving until cleared
First Month:
- Follow-up appointment for device check
- Gradual return to normal activities
- Most patients resume work
Long-Term Care:
- Remote monitoring – device transmits data from home
- Device programming checks periodically
- In-clinic checks every 6–12 months or as advised by the doctor.
- Battery replacement typically after 5–10 years
Living with an AICD:
- You'll receive a device ID card – carry it always
- Most daily activities, exercise, and travel are safe
- Inform all doctors and technicians about your device
- Cell phones: use on opposite ear, don't carry over the device
