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.

Microscopic structural changes in the aging heart may reduce risk of arrhythmias

Virginia Tech researchers at the Fralin Biomedical Research Institute at VTC have discovered that microscopic structural changes in the aging heart may reduce the risk of irregular heartbeats.

Study sheds light on why women have faster heartbeats than men

For decades, doctors and researchers have puzzled over a basic heart rhythm mystery: Why do women tend to have faster heartbeats while men are more likely to develop irregular rhythms like atrial fibrillation (AFib)?

Palliative care for cardiovascular conditions may help relieve symptoms and improve quality of life

Palliative care may help relieve symptoms and improve quality of life for people with cardiovascular disease and ensure that treatment is aligned with the patient's personal beliefs and values throughout all stages of illness, whether they are hospitalized in a cardiac intensive care unit or receiving outpatient care, according to a new American Heart Association scientific statement published today in the Association's flagship, peer-reviewed journal Circulation.

Gum disease bacterium linked to increased risk of atrial fibrillation

Tempted to skip the floss? Your heart might thank you if you don't. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart.

Study reveals regional risk factors driving heart disease in Asia and Oceania

A new study puts the spotlight on the rising burden of ischemic heart disease across Southeast Asia, East Asia and Oceania, and calls for localized, equity-focused interventions in these regions.

Cardiovascular mortality higher in women with rheumatoid arthritis and lupus

Women with the autoimmune diseases rheumatoid arthritis, lupus or systemic sclerosis may have a higher rate of death related to cardiovascular disease than men with the autoimmune diseases, according to new research published in the American Heart Association's journal Circulation: Cardiovascular Quality and Outcomes.

Study: One in four early cardiogenic shock patients experience worse outcomes

In one of the largest studies of early cardiogenic shock (CS) patients, where blood flow is still functioning to vital organs, researchers demonstrated that 26% experienced worse outcomes, including care escalation, CS deterioration, or in-hospital mortality.

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.
