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.
St. Jude Medical, Inc., a global medical device company, is pleased to again participate in the Asia-Pacific Heart Rhythm Society Scientific Session (APHRS), which is being held this year in conjunction with the Japanese Heart Rhythm Society (JHRS) and the Japanese Society of Electrocardiology (JSE) in Fukuoka, Japan.
We won't stop the rising tide of infections until we develop a new business model to fight them. We are not quite on the brink of some dystopian Victorian future. But every year, the prognosis for infectious-disease patients gets a bit grimmer. … And more-powerful drugs tend to cost more than the old drugs. … Even in the rich world, death from infection still looms; MRSA alone kills thousands every year. And firms are not developing antibiotics as fast as they used to.
Many patients are responding to a new, minimally invasive way of treating irregular heartbeats by freezing out the bad cells. Atrial fibrillation (A-Fib) is one such heart rhythm disorder, and it's the most common arrhythmia affecting Americans.
Urgent coordinated action from national governments, medical societies and patient organizations is needed to avoid a public health crisis resulting from the tide of preventable strokes that leave many people with atrial fibrillation (AF) mentally and physically disabled or dead, every year. How Can We Avoid a Stroke Crisis in Latin America?, a report from Action for Stroke Prevention - a group of health experts from around the world - reveals the huge economic, social and personal burden of AF-related strokes across the region.
The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.
St. Jude Medical, Inc., a global medical device company, today announced the approval of the industry's first quadripolar pacing system for cardiac resynchronization therapy defibrillators (CRT-Ds) in India. The Promote Quadra CRT-D offers physicians the ability to more effectively and efficiently manage the ever-changing pacing needs of patients with heart failure.
UC Davis researchers have developed an accurate computer model to test the effects of medications for arrhythmia, or abnormal heart rhythm, before they are used in patients.
A Swedish study presented at the ESC Congress 2011 today, found a higher incidence of arrhythmias in cross-country skiers with a long history of endurance training.
Results from the STOP-VT Study were presented at the ESC Congress 2011 today. This is the first ever multi-center, global, prospective trial to evaluate a Remote Magnetic Navigation system for the treatment of ischemic Ventricular Tachycardia.
The AF AWARE campaign today, at the European Society of Cardiology (ESC) Congress 2011 in Paris, announces the launch of the Atrial Fibrillation in Primary Care (AFIP) tool, developed to help primary care physicians (PCPs) with early diagnosis and optimal management of patients with atrial fibrillation.
New data show that, worldwide, one in three patients with atrial fibrillation (AF) who are at high risk for stroke are not being prescribed anticoagulant therapy, particularly vitamin K antagonists (VKA) – medicines known to significantly lower stroke risk in these patients.
Bristol-Myers Squibb Company and Pfizer Inc. today announced the main results of the Phase 3 clinical trial ARISTOTLE, which evaluated ELIQUIS compared to warfarin for the prevention of stroke or systemic embolism in 18,201 patients with atrial fibrillation and at least one risk factor for stroke.
W. L. Gore & Associates today reported that it has received zero accounts of erosion of the aortic root or the free wall of the atrium associated with the worldwide use of the GORE® HELEX® Septal Occluder.
These physicians are not anti-medicine. They are not trying to save money on their copayments or deductibles. And they are not trying to rein in the nation's soaring health-care costs, which at $2.7 trillion account for fully one sixth of every dollar spent in the U.S. They are applying to their personal lives a message they have become increasingly vocal about in their roles as biomedical researchers and doctors: more health care often means worse health.
By employing optogenetics, a new field that uses genetically altered cells to respond to light, and a tandem unit cell (TCU) strategy, researchers at Stony Brook University have demonstrated a way to control cell excitation and contraction in cardiac muscle cells, the details of which are published in the early online edition of Circulation: Arrhythmia & Electrophysiology: "Stimulating Cardiac Muscle by Light: Cardiac Optogenetics by Cell Delivery."
A new drug for gout could help very sick gout patients who don't get better with usual treatment, according to a new study. The research was designed and funded by the pharmaceutical company Savient, which markets the drug, called Krystexxa (pegloticase).
The latest research has revealed that a new drug for treating people with an irregular heartbeat has fewer side effects than the standard treatment and is just as good at cutting the risk of stroke. Rivaroxaban, which is easier for people to take, is as effective as warfarin at preventing blood clots and thus lowering the risk of stroke for patients with atrial fibrillation say researchers.
The Guidelines Department of the European Society of Cardiology has issued the following statement today: "The European Society of Cardiology (ESC) is aware of the early termination of the PALLAS trial because of adverse outcomes associated with dronedarone.
The compound, ursodeoxycholic acid (UDCA), is already used to lower cholesterol and help dissolve gallstones, and it's a key ingredient in many traditional Chinese medicines, which use bear bile. According to the latest research from Imperial College London it might also be able to treat abnormal heart rhythm, or arrhythmia, in fetuses and heart attack victims.
