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.
A new study has identified several common genetic variants related to a risk factor for sudden cardiac death.
You're sitting at your desk and suddenly your heart is beating in overdrive or worse, lurching along like a car on fumes.
The U.S. Food and Drug Administration is expanding, for the second time, its nationwide alert to consumers about tainted weight loss products containing
Sanofi-aventis has announced that the Cardiovascular and Renal Drugs Advisory Committee voted 10 to 3 in favor of the approval of Multaq by the U.S. Food and Drug Administration (FDA) to treat patients with non-permanent atrial fibrillation (AF).
A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC).
A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC.) Reported in the March 12 issue of The New England Journal of Medicine ( NEJM ), the new findings offer the possibility of a highly sensitive and specific means of identifying this life- threatening condition at an early stage, when it can be treated with by implanting a cardiac defibrillator.
Even for those without a heart condition, it's a peculiar feeling when your heart "races" in response to stress.
New data published in the March 17, 2009, issue of the Journal of the American College of Cardiology suggest that relatively healthy women with severe depression are at increased risk of cardiac events, including sudden cardiac death (SCD) and fatal coronary heart disease (CHD).
Chronic kidney disease increases the risk of stroke in patients with atrial fibrillation (AF), the most common type of heart arrhythmia, according to a new study by Kaiser Permanente researchers in the current online issue of Circulation.
A recent study in Oregon suggests that drugs designed for treating the most severe mental illnesses are often prescribed at inappropriately low doses and at considerable expense, for use in conditions where their benefit has not been established.
Cordex Pharma, Inc. has announced today that it has filed a formulation patent covering its lead product, ATPace.
Before flying off the handle the next time someone cuts you off in traffic, consider the latest research from Yale School of Medicine researchers that links changes brought on by anger or other strong emotions to future arrhythmias and sudden cardiac arrests, which are blamed for 400,000 deaths annually.
David H. Adams, MD, Marie-Josée and Henry R. Kravis Professor and Chairman of the Department of Cardiothoracic Surgery at The Mount Sinai Medical Center, performed the first two implantations of the Carpentier-Edwards Physio II ring in the United States yesterday.
Following a review by The Lancet of the medical issues associated with commercial air travel, the European Society of Cardiology has reaffirmed its advice about the risks of venous thromboembolism (VTE), whose risk, according to The Lancet, is increased "up to four-fold" by long-haul flight.
New research published in the March 3, 2009, issue of the Journal of the American College of Cardiology finds that anger-induced electrical changes in the heart can predict future arrhythmias in patients with implantable cardioverter-defibrillators (ICDs).
Results from the ATHENA trial, reported in the 12th February issue of the New England Journal of Medicine , suggest that the (as yet unlicensed) antiarrhythmic drug dronedarone can reduce the incidence of cardiovascular-related hospitalisation or death in patients with atrial fibrillation.
The U.S. Food and Drug Administration has approved the first ablation catheters for the treatment of atrial fibrillation (uncoordinated contractions of the upper heart chambers), one of the most common types of arrhythmias-or abnormal heart rhythms--affecting more than two million Americans.
Abnormal heart rhythms - arrhythmias - are killers. They strike without warning, causing sudden cardiac death, which accounts for about 10 percent of all deaths in the United States.
Pfizer Inc. has agreed to provide the University of Rochester Medical Center (URMC) with a unique set of electrocardiographic data that will help researchers develop new methods to ensure the safety of experimental drugs.
Implantable cardioverter defibrillators (ICDs) can improve survival in patients with heart damage - even those in their 70s - according to research reported in Circulation: Cardiovascular Quality and Outcomes.
