An electronic device that is used to constantly monitor the heart rhythm is known as an implantable cardioverter defibrillator or ICD. When a very fast heart rhythm is detected, energy is delivered by the ICD to the heart muscle, allowing the heart to beat in a normal rhythm once again.
An ICD is required if you have a very fast heartbeat that prevents the heart from supplying blood to the rest of the body, or if you are at an increased risk of developing arrhythmia or heart rhythm problems because of a weak heart muscle.
Types:
Purpose:
An ICD may be used in the following cases:
Ventricular fibrillation (quivering or erratic pumping of blood)
Ventricular tachycardia (an extremely fast heart rhythm)
Previous heart attack
History of heart disease
Cardiomyopathy (enlarged or thickened heart muscle)
Heart failure
Inherited, congenital (present at birth) heart defects like long QT syndrome
The symptoms that start to appear which indicate the requirement of an ICD are-
Pain in the chest
Tachycardia and Bradycardia
Dizziness and Weakness
Shortness of breath
Fainting
Sweating
High blood pressure
Sleep apnea
The procedure can be performed in two different ways:
1. Endocardial or transvenous approach:
2. Epicardial or surgical approach:
Once the leads are in place, they are tested by the doctor to make sure that they are working properly and are in the right place.
Small amounts of energy are sent through the leads into the heart, causing the contraction of the heart. This is known as the lead function test or pacing.
After the leads have been tested, the doctor connects them to the ICD device.
The doctor then uses a programmer or external device for making the final device settings.
The procedure may take two to four hours to complete.

Types:
The different types of ICD include:
The heart has four chambers, the upper chambers are known as the atrium (right and left), and the lower chambers are known as the ventricles (right and left). Depending on the heart chamber that the ICD sends electrical signals to, the different types of ICD include:

An implantable cardioverter-defibrillator is a pager-sized device which is placed in the patient's chest to reduce his or her risk of dying if the lower chambers of their heart go into a dangerous rhythm and stop beating effectively, leading to cardiac arrest.
An ICD is surgically placed under the patient's skin, usually below his or her left collarbone. One or more flexible, insulated wires run from the ICD through the patient's veins to his or her heart. Because the implantable cardioverter-defibrillator constantly monitors for abnormal heart rhythms and instantly tries to correct them, the device helps treat cardiac arrest, even when the patient is far from the nearest hospital
A pacemaker is a small device that’s placed under the skin of the patient's chest or abdomen to control abnormal heart rhythms. An ICD is a small device placed in your chest or abdomen if you have an irregular heartbeat or are at risk for sudden cardiac arrest. The biggest difference between an ICD and pacemaker is that pacemakers only give low-energy electrical pulses to restore a regular heartbeat but an ICD continually monitors heart rhythm and can send low- or high-energy electrical pulses to correct abnormal heart rhythm. ICDs initially send low-energy pulses to restore heart rhythm. But they switch to high-energy pulses when the low-energy shocks are ineffective.
ICDs are more effective if you are at high risk for or with a history of sudden cardiac arrest and may need these more powerful, high-energy electrical pulses to restore your regular heartbeat. In addition to that, most new ICDs can act as both a pacemaker and a defibrillator.

ICDs initially send low-energy pulses to restore heart rhythm. But they switch to high-energy pulses when the low-energy shocks are ineffective.
A small incision, approximately 2 to 4 inches long, is made in the upper chest area, just below the collarbone. 1 or 2 leads are guided through a vein into the heart and are connected to the defibrillator. The defibrillator settings are programmed, and the device is tested to ensure it is working properly to meet the patient's medical needs. The defibrillator is inserted beneath the skin, and the incision in the chest is closed.
The procedure to implant a defibrillator does not require open heart surgery, and most people go home within one day.
Before the surgery, medication can be given to make the patient sleepy and comfortable. Generally, the ICD surgery is performed under local anesthesia.
A person may need an ICD if he or she has a dangerously fast heartbeat or a chaotic heartbeat that keeps their hearts from supplying enough blood to the rest of their body (ventricular fibrillation). A person can be a candidate for an ICD if he or she had sustained ventricular tachycardia, survived a cardiac arrest, or fainted from ventricular arrhythmia.
Although uncommon, several risks are associated with ICD implantation:
