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.
Radiation therapy often is used to treat cancer patients. Now, doctors at Washington University School of Medicine in St. Louis have shown that radiation therapy - aimed directly at the heart -; can be used to treat patients with a life-threatening heart rhythm.
Some heart disease patients face a higher risk of sudden cardiac death, which can happen when an arrhythmia -- an irregular heartbeat-- disrupts the normal electrical activity in the heart and causes the organ to stop pumping.
A groundbreaking Loyola Medicine study suggests that a simple 15-minute electrocardiogram could help a physician determine whether a patient has major depression or bipolar disorder.
Obesity is often attributed to a simple equation: People are eating too much and exercising too little. But evidence is growing that at least some of the weight gain that plagues modern humans is predetermined.
The Food and Drug Administration (FDA) is encouraging people to be careful how much black licorice they eat if they are planning to snack on the candy over Halloween.
A new clinical study on the early detection of atrial fibrillation at home is starting at the German Centre for Cardiovascular Research. This cardiac arrhythmia is responsible for a quarter of all strokes and yet the risk of patients with atrial fibrillation having a stroke can be reduced by 70 percent if they take anticoagulants early enough.
Atrial fibrillation is the most prevalent form of cardiac arrhythmia, affecting up to 6 million people in the U.S. alone. Common treatments for severe forms of the erratic beating phenomenon are controversial, and guided by detection methods that are not yet standardized or fully refined.
A pilot program that uses big data to predict which lung cancer patients will require a trip to an emergency department successfully anticipated a third of all ED visits over a two-week trial period, and was further able to identify which patients were at high risk and low risk of requiring such care.
The VTT spin-off, VitalSignum, is making a small mobile device - which detects arrhythmia by measuring the patient's ECG - available to consumers. The first production batch is being completed and will be retailed to consumers in early October.
A study involving cardiac patients at the University Hospital of Umeå shows that over 80 percent of patients treated for atrial fibrillation also have sleep apnea - a condition with pauses in breathing during sleep.
A group of researchers from MIPT and Ghent University(Belgium) has developed the first realistic model able to reproduce the complexity of the cardiac microstructure.

While the development of therapies designed to block "checkpoints" within the immune system has been one of the most exciting and noteworthy advances in cancer research in recent years, it's also been one of the most puzzling, leaving researchers to ask: Why don't these new therapies work for more patients, and why is their efficacy in controlling cancerous tumors often short-lived? A research team from Roswell Park Cancer Institute has shown that at least one answer -; and an excellent opportunity for unleashing the full potential of these promising immunotherapies -; may lie in the body's "fight or flight" reaction to stressors and in drugs already widely used to control and temporarily disable this stress response.
Every year millions of people around the world are diagnosed with heart failure, a chronic, progressive condition where the heart is unable to pump enough oxygenated blood throughout the body.
During the "Novel Implications for Blood Flow and Vascular Dysfunction in Non-cardiovascular Related Disease" symposium at the APS Cardiovascular Aging: New Frontiers and Old Friends conference, researchers will present findings that emphasize the interaction between age-related cardiovascular dysfunction and disease whose risk increases with age.
A new study indicates that individuals with kidney disease have a higher risk of developing atrial fibrillation, or an irregular heartbeat.
Peerbridge Health has the vision to remove all wires associated with monitoring patients. For example, typically, electrocardiogram (ECG) monitoring systems have a multitude of wires. They started building a wireless ECG monitoring system called the Peerbridge Cor™ to improve ECG monitoring from the ground up.
Arrhythmia Alliance is calling on NHS England to reconsider its ‘Commissioning through Evaluation’ (CtE) process, which has left hundreds of patients with AF (Atrial Fibrillation) at serious risk of suffering a debilitating or life-threatening AF-related stroke.
There's good news when it comes to our heart's sinoatrial node (SAN), the body's natural pacemaker. Scientists at The Ohio State University Wexner Medical Center have shown the human SAN is hardwired with a backup system -- three diverse regions of pacemakers acting as batteries and up to five conduction pathways that act as wires to connect the signal to the atria.
A five per cent difference in favor of the 48 hours. This is the result of a study from Aarhus University that has spent several years examining the possible benefits of cooling down patients suffering cardiac arrest to 33°C for 48 hours, instead of the 24-hours that is standard practice in most places.
