A cardiac pacemaker, is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers to contract and therefore pump blood; by doing so this device replaces and/or regulates the function of the electrical conduction system of the heart.
Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current to the heart. Although not fully understood, this process depolarizes a large amount of the heart muscle, ending the dysrhythmia. 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 a defibrillator, but would be treated by cardiopulmonary resuscitation (CPR).
An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform cardioversion, defibrillation, and pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias. 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. Current devices can be programmed to detect abnormal heart rhythms and deliver therapy via programmable antitachycardia pacing in addition to low-energy and high-energy shocks.
Cardiac electrophysiology is the science of elucidating, diagnosing, and treating the electrical activities of the heart. The term is usually used in a clinical context to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation (PES), see Clinical cardiac electrophysiology. Cardiac electrophysiology also encompasses basic research and translational research components. Someone who studies cardiac electrophysiology, either clinically or solely through research, is known as a cardiac electrophysiologist.
Guidant Corporation, part of Boston Scientific and Abbott Labs, designs and manufactures artificial cardiac pacemakers, implantable cardioverter-defibrillators, stents, and other cardiovascular medical products. Their company headquarters is located in Indianapolis, Indiana. Their main competitors are Medtronic, St. Jude Medical, and Johnson and Johnson.
T wave alternans (TWA) is a periodic beat-to-beat variation in the amplitude or shape of the T wave in an electrocardiogram TWA was first described in 1908. At that time, only large variations could be detected. Those large TWAs were associated with increased susceptibility to lethal ventricular tachycardias.
St. Jude Medical, Inc. was an American global medical device company headquartered in Little Canada, Minnesota, U.S., a suburb of Saint Paul. The company had more than 20 principal operations and manufacturing facilities worldwide with products sold in more than 100 countries. Its major markets include the United States, Europe, Latin America and Asia-Pacific. The company was named after Jude the Apostle, the patron saint of lost causes.
Michel Mirowski was a physician who helped develop the implantable cardioverter-defibrillator (ICD).
Clinical cardiac electrophysiology, is a branch of the medical specialty of cardiology and is concerned with the study and treatment of rhythm disorders of the heart. Cardiologists with expertise in this area are usually referred to as electrophysiologists. Electrophysiologists are trained in the mechanism, function, and performance of the electrical activities of the heart. Electrophysiologists work closely with other cardiologists and cardiac surgeons to assist or guide therapy for heart rhythm disturbances (arrhythmias). They are trained to perform interventional and surgical procedures to treat cardiac arrhythmia.
William P. Murphy Jr. is a medical doctor and inventor of medical devices including collaborating on a flexible sealed blood bag used for blood transfusions. He is the son of the American physician William Parry Murphy who shared the Nobel Prize in Physiology for Medicine in 1934, and Harriett Adams, the first licensed female dentist in Massachusetts.
Mir A. Imran, is an Indian medical inventor, entrepreneur and venture capitalist. Imran has formed over 20 medical device companies since the early 1980s and holds over 400 patents. He is known for his role in developing the world's first implantable cardiac defibrillator.
Morton M. Mower is an American cardiologist and the co-inventor of the automatic implantable cardioverter defibrillator. He has served in several professional capacities at Sinai Hospital and Cardiac Pacemakers Inc. In 1996, he became the chairman and chief executive officer of Mower Research Associates. He was inducted into the National Inventors Hall of Fame in 2002 for the development of the automatic implantable cardioverter defibrillator with Michel Mirowski in the 1970s. He now continues his research in the biomechanical engineering laboratories at Johns Hopkins University.
Sinai Hospital is an American private hospital based in Baltimore, Maryland, that was founded in 1866 as the Hebrew Hospital and Asylum. It is now a Jewish-sponsored teaching hospital that provides care for patients in the greater Baltimore City, Baltimore County and surrounding communities. The implantable cardioverter-defibrillator (ICD) was invented here by the team of Dr. Michel Mirowski, Dr. Morton Mower, M. Stephen Heilman, and Alois Langer who are all in the National Inventors Hall of Fame for their achievement.
Alois A. Langer is an American biomedical engineer best known as one of the co-inventors of the Implantable Cardioverter Defibrillator (ICD).
Cardiac resynchronisation therapy is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the interior chest wall.
A wearable cardioverter defibrillator (WCD) is a device worn by patients who are at risk for sudden cardiac arrest (SCA). A WCD allows physicians time to assess for their patient's arrhythmic risk and make appropriate plans.
Biotronik is a privately held multinational biomedical technology company headquartered in Berlin, Germany.
Cameron Health was a medical device developer based in San Clemente, California, USA. Cameron Health had its European office, Cameron Health BV, in Arnhem, The Netherlands. The privately held company's focus was on a new generation of minimally invasive implantable cardioverter-defibrillator (ICD) which they called a Subcutaneous Implantable Defibrillator (S-ICD). Cameron Health's approach avoided implanting transvenous leads into the heart, which had been the usual procedure for cardiac devices. Instead, the Cameron ICD was entirely implanted outside the thoracic wall.
Yaariv Khaykin is a Canadian cardiologist and a clinical researcher in the area of electrophysiology. He is the director of the Newmarket Electrophysiology Research Group at the Southlake Regional Health Centre. He has published research into complex ablation and pioneered cardiac ablation methods.
Cyborg data mining is the practice of collecting data produced by an implantable device that monitors bodily processes for commercial interests. As an android is a human-like robot, a cyborg, on the other hand, is an organism whose physiological functioning is aided by or dependent upon a mechanical/electronic device that relies on some sort of feedback.
