Arrhythmia News and Research

RSS

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.

UCLA-led consortium receives $8.6 million NIH grant to map the heart's nervous system

A consortium directed by UCLA's Dr. Kalyanam Shivkumar has received a three-year, $8.6 million grant from the National Institutes of Health to map the heart's nervous system.

Brazilian researchers propose new way for treating thalassemia major

Iron accumulation in myocardial cells, potentially resulting in heart failure or fatal arrhythmia, is one of the complications most feared by patients with thalassemia major, a hereditary disease also known as Mediterranean anemia.

New suite of sensors can help monitor patients to prevent heart failure events

A suite of sensors can predict heart failure events by detecting when a patient's condition is worsening, according to Dr. John Boehmer, professor of medicine, Penn State College of Medicine, who presented the findings at the American Heart Association annual meeting in New Orleans.

Researchers develop more efficient system for detecting and treating atrial fibrillation

Researchers at the Polytechnic University of Valencia and Hospital Gregorio Marañón in Madrid have partnered to develop a more efficient system for detecting and treating atrial fibrillation that will be in hospitals soon.

How toxic is your stress?

The term “stress” originates not in our minds or bodies, but from physics. It is the internal forces generated in an object in response to an external load. In the 1950s, Hans Selye adopted the term to characterize how living organisms change...

New treatment strategy effective in preventing bleeding in AF patients who underwent PCI, study shows

A new study led by clinician-researchers at Beth Israel Deaconess Medical Center testing the safety and effectiveness of anticoagulant strategies for patients with atrial fibrillation who undergo stenting procedures has shown that therapies combining the anticoagulant drug rivaroxaban with either single or dual anti-platelet therapy were more effective in preventing bleeding complications than the current standard of care.

Women with CHD more likely to have safe and healthy pregnancies, study finds

Congenital heart disease (CHD), a group of abnormalities in the heart that develop before birth - including holes in the heart, leaky or narrow valves, and incomplete or missing parts - affects nearly one percent of all babies born in the United States each year - upwards of 40,000 infants.

Catheter ablation lowers long-term risk of recurrent stroke in atrial fibrillation patients, research shows

Atrial fibrillation patients with a prior history of stroke who undergo catheter ablation to treat the abnormal heart rhythm lower their long-term risk of a recurrent stroke by 50 percent, according to new research from the Intermountain Medical Center Heart Institute.

Experts to discuss use of holograms and 3D printing at EuroEcho-Imaging 2016

EuroEcho-Imaging 2016 brings advanced techniques to the bedside with international experts set to discuss the use of holograms and 3D printing to guide interventions.

Immune checkpoint cancer therapies may cause rare cardiac side effects linked to unexpected immune response

Combination therapy utilizing two approved immunotherapy drugs for cancer treatment may cause rare and sometimes fatal cardiac side effects linked to an unexpected immune response.

New studies support secretoneurin as new biomarker for cardiovascular disease

Scandinavian cardiovascular diagnostics specialist CardiNor AS today announced two new studies have been published by the group at Akershus University Hospital led by Professor Torbjørn Omland and Associate Professor Helge Røsjø in leading journals that strongly support secretoneurin as a new, important biomarker for cardiovascular disease.

Biomedical engineers harvest bacterial genes that can improve electrical signaling in human cells

Duke University biomedical engineers have harvested genes for ion channels from bacteria that, with a few tweaks, can create and enhance electrical signaling in human cells, making the cells more electrically excitable.

Researchers develop new 4D flow imaging technique that helps predict stroke risk

Affecting 33.5 million patients worldwide, atrial fibrillation is the most common form of cardiac arrhythmia. As if having an irregular heart beat wasn't troubling enough, patients with atrial fibrillation are also much more likely to have a stroke.

New molecular biology technique could help identify virus-fighting potential of existing drugs

A new, computer-based screening method could reveal the virus-fighting potential of drugs originally developed to treat other conditions, reports a study in PLOS Computational Biology.

Duke, Wisconsin and UAB researchers create bioengineered patches to treat heart failure

The heart cannot regenerate muscle tissue after a heart attack has killed part of the muscle wall, and that dead tissue can strain surrounding muscle, leading to a lethal heart enlargement.

Three-dimensional heart patches may soon move closer to clinical application

The promise of stem cells to treat cardiovascular disease may soon be a step closer to clinical application as scientists from three institutions seek to perfect and test three-dimensional "heart patches" in a large animal model — the last big hurdle before trials in human patients.
