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.
eCardio Diagnostics, a leading provider of remote cardiac arrhythmia monitoring, was among eight corporate sponsors teaming up with the Heart Rhythm Society to raise the level of awareness for heart rhythm disorders, particularly Atrial Fibrillation (AF) and Sudden Cardiac Arrest.
Micah True, legendary ultra-marathoner, died suddenly while on a routine 12-mile training run March 27, 2012. The mythic Caballo Blanco in the best-selling book, Born to Run, True would run as far as 100 miles in a day. On autopsy his heart was enlarged and scarred; he died of a lethal arrhythmia (irregularity of the heart rhythm). Although speculative, the pathologic changes in the heart of this 58 year-old veteran extreme endurance athlete may have been manifestations of "Phidippides cardiomyopathy," a condition caused by chronic excessive endurance exercise.
Results observed from pre-specified interim analyses of the randomized, placebo-controlled Phase 3 study, COU-AA-302, demonstrated that patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate (ZYTIGA) plus prednisone showed a statistically significant improvement in radiographic progression-free survival (rPFS) and all secondary endpoints compared to patients treated with placebo plus prednisone.
The term "holiday heart syndrome" was coined in a 1978 study to describe patients with atrial fibrillation who experienced a common and potentially dangerous form of heart palpitation after excessive drinking, which can be common during the winter holiday season. The symptoms usually went away when the revelers stopped drinking. Now, research from UCSF builds on that finding, establishing a stronger causal link between alcohol consumption and serious palpitations in patients with atrial fibrillation, the most common form of arrhythmia.
Advanced Cardiac Therapeutics, Inc., a developer of innovative temperature-sensing cardiac ablation systems, today announced results of several studies related to the company's TEMPASURE cardiac ablation catheter.
Two studies that included adults with obstructive sleep apnea examined the effectiveness of reducing the risk of cardiovascular outcomes, including high blood pressure, by treatment with continuous positive airway pressure (CPAP), according to the articles in the May 23/30 issue of JAMA.
Use of inhaled anticholinergics (IACs) has been associated with an increased risk of potentially dangerous heart arrhythmias among young asthma patients, according to a study conducted by researchers at the University of Illinois at Chicago.
The American Association of Critical-Care Nurses (AACN) will present the Flame of Excellence Award to Carol Jacobson, RN, MN, for her efforts to educate progressive care and critical care nurses in the care of patients with cardiac disease.
Even though hundreds of thousands more people finished grueling 26.2 mile marathons in the United States in 2009 compared to a decade earlier, a runner's risk of dying during or soon after the race has remained very low — about .75 per 100,000, new Johns Hopkins research suggests. Men, however, were twice as likely to die as women.

A large cohort study has found that the strongest risk factors for atrial fibrillation in both men and women were a history of palpitations and hypertension. While hypertension is a well known risk factor for AF, the investigators note that "the impact of self-reported palpitations on later occurrence of AF has not been documented earlier".
A study conducted at Scripps Health has found that a novel new heart monitoring device helped emergency room patients avoid unnecessary follow-up care. Scripps Health electrophysiologist Steven Higgins, MD, presented findings of the study titled, "Prevalence of Arrhythmias in Emergency Department Patients Discharged Using a Novel Ambulatory Cardiac Monitor", today at the Heart Rhythm Society's 33rd Annual Scientific Sessions in Boston.
Patients with the heart rhythm disorder atrial fibrillation (AFib) who received first-line catheter ablation treatment had a longer arrhythmia-free interval than patients receiving antiarrhythmic drugs, the standard first-line treatment.
New research from the University at Buffalo suggests that cardiologists may have a new way to identify patients who are at the highest risk of sudden cardiac arrest, and the most likely to benefit from receiving an implantable cardiac defibrillator (ICD).
Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of cardiac arrhythmias, announced the launch of the new THERMOCOOL SF NAV irrigated ablation catheter with Curve Visualization in the United States.
A new report issued today by the American College of Cardiology Foundation (ACCF) and the Society for Cardiovascular Angiography and Interventions (SCAI) in collaboration with a dozen other professional societies provides detailed criteria to help clinicians determine when cardiac catheterization is a reasonable option for the evaluation of patients for heart disease.
Older women who have been diagnosed with an irregular heart beat are at higher risk of stroke than men. A new study led by the Research Institute of the McGill University Health Centre (RI MUHC) shows that warfarin, the most common anticoagulant therapy used to prevent stroke in patients with Atrial fibrillation (AF) may not be as effective in women, 75 years or older, as in men.
In a study that examined use of the anticoagulant medication warfarin and risk of stroke following a diagnosis of atrial fibrillation in older patients, women, especially those 75 years or older, had a higher risk of stroke than men, regardless of their risk profile and use of warfarin, suggesting that current anticoagulant therapy to prevent stroke might not be sufficient for older women, according to a study in the May 9 issue of JAMA.
Sorin Group, a global medical device company and a leader in the treatment of cardiovascular diseases, announced today at Heart Rhythm 2012, the Heart Rhythm Society's 33rd Annual Scientific Sessions, FDA approval and commercial launch of the PARADYM RF family of implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy (CRT-D) devices.
Massachusetts Governor Deval Patrick has proclaimed May to be Cardiac Arrhythmia Awareness Month, calling attention to the need for greater public awareness throughout the Commonwealth about two serious heart rhythm conditions, atrial fibrillation and sudden cardiac arrest. To support consumer education about these potentially life-threatening disease states, the Heart Rhythm Society (HRS) has launched a Boston Citywide Awareness Campaign to increase knowledge about symptoms, warning signs and available treatment options.
