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.

Mount Sinai researchers enhance AI tool to better detect heart disease risk

Mount Sinai researchers studying a type of heart disease known as hypertrophic cardiomyopathy (HCM) have calibrated an artificial intelligence (AI) algorithm to quickly and more specifically identify patients with the condition and flag them as high risk for greater attention during doctor's appointments.

Brisk walking linked to lower risk of heart rhythm disorders

A brisk walking pace, and the amount of time spent at this speed, may lower the risk of heart rhythm abnormalities, such as atrial fibrillation, tachycardia (rapid heartbeat), and bradycardia (very slow heartbeat), finds research published online in the journal Heart.

Digital twins and ECGI enhance accuracy in arrhythmia treatment

Millions of people around the world live with cardiac arrhythmias. Only in Spain, it is estimated that more than one million citizens suffer from them.

Atrial fibrillation elevates early-onset dementia risk in younger adults

New research presented at the EHRA 2025, a scientific congress of the European Society of Cardiology, shows that the presence of atrial fibrillation (AF) increases the risk of future dementia by 21% in patients diagnosed with AF under 70 and the risk of early-onset dementia (diagnosed before age 65 years) by 36%.

Machine learning identifies key comorbidities predicting premature death in IBD patients

Researchers use machine learning models to investigate patterns between multimorbidity and premature deaths among decedents with irritable bowel disease.

Gasdermin D found to play a crucial role in heart arrhythmias

Atrial fibrillation (AF) is a common form of heart arrhythmia, a serious condition in which the heart beats so fast that its upper chambers, the atria, quiver. This irregular heartbeat can increase the risk of severe conditions, including heart failure, dementia and stroke.

Simultaneous screening for hypertension and arrhythmia could prevent strokes

A group of 29 international experts says that simultaneous screening for hypertension and heart arrhythmia could prevent thousands of strokes.

Autonomic dysfunction linked to impaired gastric activity in stroke patients

Gastrointestinal complications are common in patients after ischemic stroke. Gastric motility is regulated by gastric pace-making activity (also called gastric myoelectrical activity (GMA)) and autonomic function.

Breakthrough in gene therapy could help protect against heart arrhythmias

Cardiac arrhythmias affect millions across the world and are responsible for a fifth of all deaths in the Netherlands.

Brazilian study reveals new pathways for preventing atrial fibrillation

A recent Brazilian study published in Nature Cardiovascular Research has highlighted promising pathways for preventing and treating atrial fibrillation, a condition that significantly raises the risks of stroke and dementia.

Drinking more coffee linked to reduced cognitive decline in people with atrial fibrillation

Drinking multiple cups of coffee a day may help prevent cognitive decline in people with atrial fibrillation (AFib or AF), according to new research published on Dec. 14, 2024 in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.
