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.
Lifelong anticoagulation is necessary for the prevention of stroke in patients with rhythm disturbances and with mechanical valves. Patients who have a coronary stent implanted also need the antiplatelet drugs aspirin and clopidogrel to prevent the rare but lethal complication of stent thrombosis.
Catheter ablation for atrial fibrillation (Afib) is safe and suppresses arrhythmia recurrences in 74% of patients after a single procedure, according to results from the one-year follow-up of the Atrial Fibrillation Ablation Pilot Study, the first European registry to evaluate the real-life epidemiology of catheter ablation for AFib.
CardioDx, Inc., a pioneer in the field of cardiovascular genomic diagnostics, today announced the completion of a $58 million two-tranche equity financing.
The intent of the Affordable Care Act (ACA) is to provide all Americans with medical insurance. Thirty-five million additional people will be covered, in part by government premiums and in part by making it easier for them to buy their own insurance.
Chronic obstructive pulmonary disease patients should be monitored for the onset of arrhythmia when they begin bronchodilator therapy, say the authors of a Canadian study.
Biosense Webster, Inc., a worldwide leader in the diagnosis and treatment of cardiac arrhythmias, announced the launch of the new CARTO 3 MEM (Multi-Electrode Mapping) Version in the United States.
Implantable cardioverter defibrillator use is responsible for one-third of the decline in cardiac arrests caused by ventricular fibrillation, researchers say.
CardioDx, Inc., a pioneer in the field of cardiovascular genomic diagnostics, today announced that Palmetto GBA, a national contractor that administers Medicare benefits, has established coverage for the company's Corus CAD gene expression test for the evaluation of patients presenting with typical and atypical symptoms suggestive of coronary artery disease.
Patients with atrial fibrillation who have a Chicken Wing left atrial appendage morphology are less likely to have a stroke than those with other morphologies, research suggests.
An international research team, led from the University of Leeds, has found that a common anti-angina drug could help protect the heart against carbon monoxide poisoning.
Adverse drug effects are harms caused by the use of a medication. There are many different types of ADEs, including medication errors.
Array BioPharma today announced that ARRY-797 met its primary endpoint in a randomized, placebo-controlled and active-controlled (oxycodone ER) Phase 2 clinical trial in 157 osteoarthritis patients suffering from moderate to severe knee pain despite the use of non-steroidal anti-inflammatory drugs (NSAIDs).
University of Michigan heart researchers are shedding light on a safer method for steadying an abnormal heart rhythm that prevents collateral damage to healthy cells.
Researchers have developed a new technology that could significantly improve the success rate of procedures to treat atrial fibrillation.
Researchers from UC San Diego, the University of California Los Angeles and Indiana University report having found, for the first time, that atrial fibrillation or irregular heart rhythms is caused by small electrical sources within the heart, in the form of electrical spinning tops ("rotors") or focal beats. Importantly, they found a way of detecting these key sources, then precisely targeting them for therapy that can shut them down in minutes with long lasting results.
Arrhythmias could precede exacerbations in chronic obstructive pulmonary disease, raising the possibility of a new target for management and treatment, say researchers.
The risk for hyperkalemia after succinylcholine use for urgent tracheal intubation increases the longer patients remain in the intensive care unit, research shows.
Study findings based on observations from a sleep clinic in Brazil indicate that obstructive sleep apnea may worsen during the winter months.
Avanir Pharmaceuticals, Inc. announced today that the United States Patent and Trademark Office (USPTO) has allowed a new patent that covers Avanir's product NUEDEXTA, further expanding the intellectual property portfolio for the company's lead commercial asset.
