Illustration of an implantable cardioverter-defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) is a battery-powered device that monitors electrical activity in the heart, and when an arrhythmia is detected, can deliver an electrical shock to terminate the abnormal rhythm. ICDs are used to prevent sudden cardiac death (SCD) in ...
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [ 1][ 2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart. Although not fully understood, this process depolarizes a large amount ...
A wearable cardioverter defibrillator ( WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [ 1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care. It is a leased device.
An implantable cardioverter-defibrillator ( ICD) or automated implantable cardioverter defibrillator ( AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden ...
A vestibular schwannoma ( VS ), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [ 1] Work on ICD-10 began in 1983, [ 2 ...
White coat syndrome. A white coat and scrubs. White coat hypertension ( WHT ), also known as white coat syndrome, is a form of labile hypertension [ 1] in which people exhibit a blood pressure level above the normal range in a clinical setting, although they do not exhibit it in other settings. [ 2] It is believed that the phenomenon is due to ...
36822. [ edit on Wikidata] Extracorporeal membrane oxygenation ( ECMO ), is a form of extracorporeal life support, providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of oxygen, gas exchange or blood supply ( perfusion) to sustain life. The technology for ECMO is largely ...
