An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
Merck & Co., Inc., Whitehouse Station, NJ, USA, which operates in many countries as Merck Sharp & Dohme Limited, announced today that the European Medicines Agency (EMEA) accepted for review the Company’s Marketing Authorisation Application (MAA) for regulatory approval of vernakalant intravenous (IV).
Cholesterol can affect the flow of the electrical currents that generate the heart beat, according to a study from two UBC cardiovascular researchers funded by the Heart and Stroke Foundation of BC & Yukon. The research team has just published the important discovery about the causes of cardiac arrhythmias (abnormal heartbeats) in one of the world's leading scientific journals.
Physicians at The Mount Sinai Medical Center were the first in the country to perform a non-surgical procedure using sutures to tie off a left atrial appendage (LAA), which is the source of blood clots leading to stroke in patients with atrial fibrillation (AFib). AFib is the most common sustained heart-rhythm disorder in the United States.
Sanofi-aventis Canada announced today that Multaq (dronedarone, 400 mg tablets) has received Health Canada approval for the treatment of patients with a history of, or current atrial fibrillation to reduce their risk of cardiovascular hospitalization due to this condition.
For those who suffer from fainting spells, the mysterious episodes can be quite scary. Far too often, fainting is chalked up to stress or other mental health issues. However, medical experts at Rush University Medical Center say that reoccurring fainting spells, also known as syncope, could be an important symptom that can point to a more serious, underlying cardiovascular condition.
Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology.
The latest statistics regarding the use of pacemakers and implantable cardiac devices in Europe was presented on Sunday 21 June, at EUROPACE 2009, the meeting of the European Heart Rhythm Association (EHRA) which takes place in Berlin, Germany from 21 to 24 June.
Angiotensin 1-7, a hormone in the body that has cardiovascular benefits, improves the metabolic syndrome in rats, according to a new study. The results were presented at The Endocrine Society's 91st Annual Meeting in Washington, D.C.
University at Buffalo researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.
Treating a common heart rhythm disorder by burning heart tissue with a catheter works dramatically better than drug treatments, a major international study has found.
A landmark follow-up study found that heart attack survivors who receive implanted cardioverter defribillators (ICDs) live longer the longer they have them, according to the results of alate-breaking clinical trail presented today at the annual Scientific Sessions of the Heart Rhythm Society.
Heart attack patients who develop serious arrhythmia in connection with procedures to open blocked arteries face a significantly higher risk of death for several months after the procedure, when compared to similar patients who do not develop such complications, according to new research from Duke University Medical Center.
A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation.
It is said that each of us marches to the beat of a different drum, but new Stanford University research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning.
Transcatheter valve implantation is a newly developed technique for the curative treatment of high-grade aortic stenosis.
Merck & Co., Inc. and Cardiome Pharma Corp. has announced a collaboration and license agreement for the development and commercialization of vernakalant, an investigational candidate for the treatment of atrial fibrillation.
A 12-year-old Dutch boy - bedridden for three years because of an inherited cardiac arrhythmia syndrome - can now join his friends on the soccer field thanks to a discovery made by Vanderbilt University Medical Center researchers.
