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.
When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death.
My mortality wake-up call came in a hospital after knee surgery, when I flat-lined because of a heart arrhythmia and was resuscitated by a nurse. In response to columns about those events, stories have streamed in from people who are running out of time themselves, or enduring the pain of watching loved ones fade. The deaths they face are as different as the lives they've lived, but a steady refrain runs through their emails and letters.
A large body of research has focused on the ability of oxytocin to facilitate social bonding in both marital and parenting relationships in human females. A new laboratory study, led by Dr. Ruth Feldman from Bar-Ilan University in Israel and published in the current issue of Biological Psychiatry, has found that oxytocin administration to fathers increases their parental engagement, with parallel effects observed in their infants.
Bisphenol A, a substance found in many synthetic products, is considered to be harmful, particularly, for fetuses and babies. Researchers from the University of Bonn have now shown in experiments on cells from human and mouse tissue that this environmental chemical blocks calcium channels in cell membranes. Similar effects are elicited by drugs used to treat high blood pressure and cardiac arrhythmia. The results are now presented in the journal "Molecular Pharmacology."
AliveCor, Inc. announced today at the start of the 4th annual mHealth Summit in Washington, D.C. that the company received FDA 510(k) clearance on its mobile Heart Monitor as well as CE Mark conformity. This clinical-quality, low-cost mobile ECG heart monitor, compatible with the iPhone® 4 and 4S, enables doctors to evaluate patient heart health easily, quickly and remotely.
Literally hundreds of clinical trials, including some that have gained widespread attention, have been done on the possible benefits of omega-3 fatty acids for the prevention of heart disease - producing conflicting results, varied claims, and frustrated consumers unsure what to believe.
Experts are calling into question the widespread use of digoxin for atrial fibrillation, in the wake of findings linking the drug to increased mortality.
Digoxin, a drug widely used to treat heart disease, increases the possibility of death when used by patients with a common heart rhythm problem − atrial fibrillation (AF), according to new study findings by University of Kentucky researchers. The results have been published in the prestigious European Heart Journal, and raises serious concerns about the expansive use of this long-standing heart medication in patients with AF.
Bristol-Myers Squibb and Pfizer announced today that the European Commission has approved ELIQUIS (apixaban) for prevention of stroke and systemic embolism in adult patients with nonvalvular atrial fibrillation (NVAF) with one or more risk factors.
Janssen-Cilag International NV (Janssen) announced today that the Committee for Medical Products for Human Use (CHMP) of the European Medicines Agency (EMA) has granted a positive opinion recommending approval of the oral, once-daily medication ZYTIGA for use in combination with prednisone or prednisolone in the treatment of metastatic castration-resistant prostate cancer (mCRPC), in adult men who are asymptomatic or mildly symptomatic after failure of androgen deprivation therapy and in whom chemotherapy is not yet clinically indicated.
Young first- and second-degree relatives of individuals who were victims of sudden cardiac death are at a significantly increased risk for developing cardiovascular disease, research suggests.

Researchers at the McCormick School of Engineering are part of a team that has used stretchable electronics to create a multipurpose medical catheter that can both monitor heart functions and perform corrections on heart tissue during surgery.
Physician-researchers from the Cardiac Center at The Children's Hospital of Philadelphia presented new findings on pediatric cardiovascular disease at the American Heart Association's Scientific Sessions 2012 in Los Angeles.
Cardiac arrhythmias are disturbances of the heartbeat. The heart can either go too slowly, which might make people collapse or exhausted; or too quickly.
Biogenic amines may be one of the factors responsible for symptoms such as headaches, gastro-intestinal disorders, shortness of breath, fall in blood pressure, and even unconsciousness and cardiac arrhythmia in severe cases. Histamine, one of the best known members of this group, can cause serious physical problems. Biogenic amines can be produced in the body by natural metabolic activities but are also ingested in larger quantities with food.
Adults with diabetes and multi-vessel coronary heart disease who underwent cardiac bypass surgery had better overall heart-related outcomes than those who underwent an artery-opening procedure to improve blood flow to the heart muscle, according to the results from an international study. The research was supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.
Bristol-Myers Squibb Company and Pfizer Inc. today announced that a large number of data presentations sponsored by the companies on ELIQUIS (apixaban) and the treatment of atrial fibrillation will be presented at the American Heart Association 2012 Scientific Sessions, November 3-7, 2012, in Los Angeles, California.
US study results indicate that cardiopulmonary exercise is well tolerated, even when performed by individuals with high-risk cardiovascular disease.
Canadian scientists have determined that routine electrocardiogram results for patients with atrial fibrillation - the most common form of irregular heart beat - can help doctors identify those at higher risk of adverse cardiovascular outcomes, including death.
