Implantable Cardioverter Defibrillator
An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implant (medicine), implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and cardiac pacemaker, pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. "AICD" was trademarked by the Boston Scientific corporation, so the more generic "ICD" is preferred terminology. On average ICD electric battery, batteries last about six to ten years. Advances in technology, such as batteries with more capacity or rechargeable batteries, may allow batteries to last for more than ten years. The leads (electrical cable wires connecting the device to the heart) have much longer average longevity, but can malfunction in various ways, specifically Insulator (electricity), insulation failure or fractu ...

Right Ventricle
A ventricle is one of two large chambers located toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium (heart), atrium, an adjacent chamber in the upper heart that is smaller than a ventricle. Interventricular means between the ventricles (for example the interventricular septum), while intraventricular means within one ventricle (for example an intraventricular block). In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. Structure Ventricles have thicker walls than atria and generate higher blood pressures. The physiological load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure g ...

Defibrillator
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). Defibrillation delivers a dose of electric current (often called a ''counter-shock'') to the heart. Although not fully understood, this process depolarizes a large amount of the heart muscle, ending the arrhythmia. Subsequently, the body's natural pacemaker in the sinoatrial node of the heart is able to re-establish normal sinus rhythm. A heart which is in asystole (flatline) cannot be restarted by defibrillation; it would be treated only by cardiopulmonary resuscitation (CPR) and medication, and then by cardioversion or defibrillation if it converts into a shockable rhythm. A device that administers defibrillation is called a defibrillator. In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle. Although the person may still b ...

Bernard Lown
Bernard Lown (June 7, 1921February 16, 2021) was a Lithuanian-American cardiologist and inventor. Lown was the original developer of the direct current defibrillator for cardiac resuscitation, and the cardioverter for correcting rapid disordered heart rhythms. He introduced a new use for the drug lidocaine to control heartbeat disturbances. Throughout his medical career, Lown focused on two major medical challenges: the problem of sudden cardiac death and the role of psychological stress on the cardiovascular system. His investigations led to many medical break-throughs, among them the coronary care unit. His work made possible and safe much of modern cardiac surgery, as well as a host of other innovations. In 1985, Lown accepted the Nobel Peace Prize on behalf of the International Physicians for the Prevention of Nuclear War, an organization he co-founded with Soviet cardiologist Yevgeny Chazov, who later was Minister Of Health of the USSR. Lown was Professor of Cardiology Emeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Michel Mirowski
Michel Mirowski (October 14, 1924 – March 26, 1990) was a physician who helped develop the implantable cardioverter-defibrillator (ICD). Born in Warsaw, Poland, he practiced medicine in Israel before coming to Sinai Hospital in Baltimore, Maryland. While there he collaborated with Dr. Morton Mower and later Dr. Stephen Heilman's artificial pacemaker company to develop the first implantable cardioverter-defibrillator. Early life Mirowski was born as Mordechai Frydman on October 14, 1924, in Warsaw. When Nazi Germany invaded Poland in the fall of 1939, his father renamed him as Mieczysław Mirowski to try to protect him from the anti-Semitism of the time. Later, his French wife, Anna, would call him Michel, by which he became known. To escape the Nazis, Mirowski fled to Ukraine, and for the next five years survived under the most appalling conditions. By 1944 he was an officer in a Polish regiment and returned to Poland where, as the war ended, he registered as a medical stud ...

Subcutaneous ICD
Subcutaneous implantable cardioverter defibrillator, or S-ICD, is an implantable medical device for detecting and terminating ventricular tachycardia and ventricular fibrillation in patients at risk of sudden cardiac arrest. It is a type of implantable cardioverter defibrillator but unlike the transvenous ICD, the S-ICD lead is placed just under the skin, leaving the heart and veins untouched. The S-ICD was developed to reduce the risk of complications associated with transvenous leads. Potential complications, such as infections in the bloodstream and the need to remove or replace the leads in the heart, are minimised or entirely eliminated with the S-ICD system. Transvenous ICD (leads in the heart) Pros The generator is smaller than the S-ICD generator, which may result in a less visible implanted device. This could improve the time needed to get used to the implantable device, although this is subjective. The procedure can usually be done under local anesthesia and ligh ...
