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.

Detection of atrial fibrillation after stroke made easy with electrocardiomatrix technology

Researchers have developed a new and easier method of detecting irregular heart rhythms such as Atrial Fibrillation (AF or AFib) after a stroke. At present clinical rely upon standard cardiac telemetry to detect AF seen commonly after a stroke.

Hesperos' multi-organ model correctly determine cardiotoxic mechanisms

Hesperos Inc., pioneers of the "human-on-a-chip" in vitro system has announced the use of its innovative multi-organ model to successfully measure the concentration and metabolism of two known cardiotoxic small molecules over time, to accurately describe the drug behavior and toxic effects in vivo.

Novel population-based approach to examine families where AF occurs with left atrial fibrosis

Atrial fibrillation is a condition that produces an irregular heartbeat that affects about two percent of the general population and six percent of people over 65 years of age.

Study identifies risk factors for cardiotoxicity with relapsed multiple myeloma therapy

More than half of patients with relapsed multiple myeloma treated with carfilzomib experienced cardiac issues during treatment, according to a multi-institutional study published June 12 in Journal of Clinical Oncology.

Heart failure drug could be effective in treating leukemia

Canadian researchers followed their intuition that a drug initially intended for heart failure could be effective in treating cancer. Those efforts have borne fruit, as demonstrated by their work published in the Journal of Experimental and Clinical Cancer Research.

UA physician-scientist receives grant to study sleep apnea and heart health

Obstructive sleep apnea is a common condition that has been associated with increased mortality, especially in individuals who have cardiac arrhythmia. A University of Arizona physician-scientist has received a grant to try to find out why.

Fainting during pregnancy may indicate issues for both the baby and mother's health

Women have long been told fainting is a common but harmless symptom of pregnancy, but new research shows it may indicate issues for both the baby and mother's health, especially when it occurs during the first trimester.

Energy drinks may increase blood pressure and risk of electrical disturbances in heart

Drinking 32 ounces of an energy drink in a short timespan may increase blood pressure and the risk of electrical disturbances in the heart, which affect heart rhythm, according to a small study published in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Fainting during pregnancy could be more serious than earlier believed finds study

Fainting spells especially early in the pregnancy could indicate health problems for the mother and baby later says a new study. Earlier short spells of black outs or syncope were considered to be normal during early pregnancy.

New algorithm guides catheters to accurately locate atrial fibrillation sources

Patients with atrial fibrillation or AFib experience chaotic electrical signals in the upper chamber of their heart (atria), which cause an irregular or quivering heartbeat (arrhythmia) that can lead to blood clots and heart failure. AFib also is a major cause of stroke and affects 33 million people worldwide.

Study aims to optimize device implantation in patients with atrial fibrillation and stroke risk

According to clinical studies, about a third of patients with atrial fibrillation will suffer a stroke during their lifetime. Between 70 and 90% of these strokes are caused by a thrombus formed in the left atrial appendage.

Bariatric surgery before AF ablation reduces arrhythmia recurrence risk

A new study shows that overweight patients who have bariatric surgery before undergoing ablation reduce their risk of the arrhythmia returning.

Web-based intervention opens way to improve well-being of heart-failure patients

Many patients with an implantable cardioverter defibrillator(ICD) are anxious of the shock delivered by the device to stop life-threatening ventricular arrhythmia or fibrillation.

Stress-related disorders increase risk of cardiovascular disease by 60%

A new study has found that stress-related disorders are associated with an increased risk for multiple types of cardiovascular disease, including atherosclerosis (narrowing of the arteries).

Stress related disorders linked to multiple types of cardiovascular disease

A group of researchers followed up a population of siblings and tried to estimate the connection between stress-related conditions and heart disease. Their study titled “Stress related disorders and risk of cardiovascular disease: population based, sibling controlled cohort study,” was published in the latest issue of the journal BMJ.

Scientists identify biomarkers to predict risk of atrial fibrillation

Scientists at the University of Navarra (Spain), in collaboration with clinicians from the University Hospital of Donostia, have identified two biomarkers associated with the risk of suffering atrial fibrillation, a cardiac ailment that affects more than 33.5 million people in the world.

New computer program predicts risk of life-threatening arrhythmias

Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers from Johns Hopkins has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit--or not--from lifesaving implanted defibrillators.

Lithuanian researchers develop smart wrist-worn device for monitoring atrial fibrillation

Although smart wristbands are popular fashion gadgets for monitoring heart rate and physical activity, they are usually not sophisticated enough to provide specific and accurate information about potential health problems of the wearer.

Simplified catheter ablation could slash waiting lists for atrial fibrillation patients

A day case catheter ablation procedure which includes only the bare essentials and delivers the same outcomes could slash waiting lists for atrial fibrillation patients, according to late-breaking results from the AVATAR-AF trial presented today at EHRA 2019, a European Society of Cardiology congress.
