AICD ImplantAutomatic Implantable Defibrillator

A life-saving, smart implantable device designed to continuously monitor your heart rhythm and instantly deliver electrical therapy to prevent sudden cardiac death.

What is an AICD (Implantable Defibrillator)?

An Automatic Implantable Cardioverter-Defibrillator (AICD) is a sophisticated, life-saving electronic device implanted beneath the skin of the chest. It monitors your heart rhythm continuously, 24/7. If it detects a life-threatening, chaotic fast heartbeat (such as Ventricular Tachycardia or Ventricular Fibrillation), the device automatically discharges a corrective electrical pulse or high-energy shock to reset the rhythm back to normal, preventing sudden cardiac arrest.

THERAPEUTIC MATRIX

How an AICD Protects Your Heart

1. Anti-Tachycardia Pacing (ATP)

If a fast but stable arrhythmia is sensed, the device sends small, imperceptible pacing signals to gently guide the heart back into rhythm.

2. Cardioversion Shocks

For rapid, organized ventricular rhythms, the device delivers a synchronized low-energy shock to terminate the abnormal rhythm.

3. Defibrillation Shocks

In cases of ventricular fibrillation (chaotic fluttering), the device instantly discharges a high-energy shock to restore a normal heartbeat.

4. Backup Bradycardia Pacing

If your heart rate drops too low following a shock or arrhythmia event, the AICD behaves like a standard pacemaker to maintain your pulse.

INDICATIONS FOR THERAPY

Who Needs an AICD Implantation?

Sudden Cardiac Arrest SurvivorsPatients who have survived a previous cardiac arrest event caused by rapid, life-threatening ventricular arrhythmias.
Severely Reduced Heart FunctionIndividuals with heart failure who present with an ejection fraction (pumping capacity) of less than 35%.
Ventricular Tachycardia & FibrillationPatients diagnosed with episodes of dangerous, fast heart rhythm disorders originating in the lower chambers (ventricles).
Inherited Cardiac Risk ConditionsGenetic conditions like Hypertrophic Cardiomyopathy (HCM), Brugada Syndrome, or Long QT Syndrome that increase sudden death risks.
COMPARATIVE MATRIX

AICD vs. Pacemaker

Pacemakers are designed to correct slow heart rhythms (bradycardia), sending small pulses to stimulate regular contraction.

AICDs target rapid, life-threatening heart rhythms (tachycardia or fibrillation), delivering precise shocks to prevent sudden cardiac arrest.

Many modern AICD systems also integrate standard pacemaker features, delivering backup slow-rate pacing support when needed.

I had an amazing experience with Dr. Subhash. My father's Coronary Calcium score was way too high but he was asymptomatic. Dr. explained everything in very detail and went above and beyond to do the very best he could. He checked all the alternatives available and advised us the best. He answered all the doubts I had and made it very clear for us what next steps should be taken.
