AICD ( Automatic implantable cardioverter defibrillator )

An Automatic Implantable Cardioverter Defibrillator (AICD) is a small electronic device implanted in the chest to monitor heart rhythm continuously and treat life-threatening abnormal heartbeats. If a dangerous rhythm such as ventricular tachycardia or ventricular fibrillation occurs, the AICD automatically delivers an electrical shock to restore a normal heartbeat.

Who Needs an AICD?

An AICD may be recommended for patients who:

• Are at high risk of sudden cardiac arrest

• Have a history of ventricular arrhythmias

• Have survived a previous cardiac arrest

• Have severe heart muscle weakness (low ejection fraction)

• Have certain inherited or structural heart conditions

  How Does an AICD Work?

• Continuous Monitoring: Tracks heart rhythm 24/7

• Anti-Tachycardia Pacing (ATP): Corrects fast rhythms without shock when possible

• Defibrillation Shock: Delivers a life-saving shock if a dangerous rhythm is detected

• Pacing Support: Prevents slow heart rates when needed
