Implantable Cardioverter Defibrillators | Community Health

Implantable cardioverter defibrillators (ICDs) are medical devices implanted inside the body to prevent sudden cardiac death by performing defibrillation, cardioversion, and pacing of the heart. They are the first-line treatment and prophylactic therapy for patients at risk for ventricular fibrillation and ventricular tachycardia. With advances in technology, ICD batteries can last from six to ten years, and newer models may have even longer battery life. The devices are connected to the heart through leads, which have a longer average longevity but may require replacement every 5 to 10 years due to potential malfunctions. ICDs have revolutionized the treatment of heart conditions, saving countless lives and improving the quality of life for patients with cardiac conditions. According to the [[american-heart-association|American Heart Association]], ICDs are a crucial part of the treatment plan for patients with heart failure, and [[boston-scientific|Boston Scientific]] has been at the forefront of ICD technology. The development of ICDs has also been influenced by the work of [[marie-curie|Marie Curie]], who pioneered research in [[radioactivity|radioactivity]] and paved the way for the use of radioactive isotopes in medical devices. As of 2022, over 100,000 ICDs have been implanted worldwide, with a significant increase in implantation rates over the past decade. The [[national-institutes-of-health|National Institutes of Health]] has also played a crucial role in funding research and development of ICD technology.
