  2. What is an implantable cardioverter- defibrillator? • An implantable cardioverter-defibrillator or ICD refers to a device that helps to regulate the heart.

  3. Problems the ICD Solve • ICD’s are used to treat ventricular tachycardia and ventricular fibrillation. • ICD’s have aided with the prevention of sudden cardiac death in adults. • Used to treat arrhythmias- atrial flutter, atrial fibrillation. • Brugada Syndrome • Long QT Syndrome • Bradycardia • Sick Sinus Syndrome

  4. History of the ICD • ICD was invented by Michael Mirowski. It was prompted by the sudden death of a colleague. After building a prototype device, it was tested and refined in animals. • Initially introduced to humans in 1980 despite skepticism and criticism. • Early batteries only lasted for two years or less. • Approved by the FDA in 1985 • Initial ICD devices were large and bulky. • Early devices were known as “shock boxes”. • Technological advances have made ICD more convenient and safe. • Initially, was used as a last resort treatment. • February 2008, the smallest patient ever received the ICD procedure. The patient was a five week old infant weighing in at 4.9 kg.

  5. Current Technology • The ICD pulse generator is a battery powered computer like device that is about the size of a Mason jar lid. • One or two lead wires will connect the heart muscle to the pulse generator. • ICD continuously monitors the heart for any abnormalities.

  6. Methods • The ICD generator is implanted under the skin, beneath the shoulder. It can also be implanted in the abdominal area. • A single chamber ICD will have one lead in the ventricle. • A dual chamber ICD will have two leads in both the atrium and ventricle. • In order to test the ICD, doctors will induce arrhythmia. During this time, the patient will be put under. • Once the test is complete, the doctor will close the incision where the ICD is placed. • Different shocks will perform different jobs for the ICD.

  7. To determine whether or not you may need an ICD, doctors will diagnose you by different means. • Current device batteries are expected to live up to 6 years or longer. • Most people who use it do not have any daily concerns with living with an ICD. • After a 6-24 month period after operation, most patients had successful transitions with their lives. • The minimum patient weight requirements is 10kg, but the ideal weight is 15-20kgs.

  8. Limitations • The price of an ICD may cost from $10,000-$100,000. It depends on the maker of the device and the function. • Some complications may occur after operation that will require medical attention. • An ICD does not interfere with everyday life, but has a psychological impact. • Women were more susceptible to having troubles with coping and having anxiety. • Shocks from the ICD produce fear and anxiety. • Children are too vulnerable to the complications of the ICD, whether internal or external.

  9. Future of ICD • The price of the ICD will be lowered and become more accessible. • The size of the pulse generator will be reduced, becoming more convenient. • The battery life will be prolonged. • The device will become more useful in pediatrics, and become a primary option for children.
