An AICD is a small device implanted in patients at high risk of life-threatening arrhythmias. It continuously monitors the heart rhythm and delivers an electric shock to restore normal rhythm if a dangerous irregular heartbeat occurs. Patients with prior cardiac arrest, ventricular tachycardia, or severe cardiomyopathy benefit from this life-saving therapy. Dr. Bhaimangesh Naik ensures careful device selection, implantation, programming, and follow-up to maximize safety and effectiveness.
