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.
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.
Canadian researchers have suggested that the evidence which supports the protective benefit of fish oil is inconclusive and more research is needed.
The University of California, San Diego Medical Center is the first hospital in California to enroll patients in a multi-center clinical trial, sponsored by Angioblast Systems Inc., to examine the safety and feasibility of administering adult stems cells to treat congestive heart failure.
Hundreds of millions of people, mainly in developing countries, are disabled by infectious diseases, according to the World Health Organization.
Results from a Phase 3 study show that patients with metastatic breast cancer who were treated previously with an anthracycline in the adjuvant setting experienced a significant improvement in time to disease progression (TTP) and overall response rates after receiving a combination of DOXIL (doxorubicin HCl liposome injection) and docetaxel as compared to docetaxel alone.
A University of Iowa study provides insight into a calcium-sensing enzyme already known to play a role in irregular heartbeats and other critical functions.
A new study shows that atrial fibrillation--the most common form of sustained heart arrhythmia--can be caused in an unexpected way.
Researchers at the Burnham Institute for Medical Research have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function.
When treatment options dwindle or are exhausted, terminally ill-patients often opt for pain management and comfort over life-extending therapies.
