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.

Study shows atrial fibrillation more dangerous in younger population

Atrial fibrillation (Afib), a common type of arrhythmia that is on the rise in people under the age of 65, is more dangerous in this increasingly younger population than previously thought, according to a new study published today in Circulation Arrhythmia and Electrophysiology and authored by physician-scientists at the UPMC Heart and Vascular Institute.

Study shows antipsychotic drugs increase health risks in dementia patients

Study found that antipsychotic drug use in dementia patients is linked to increased risks of stroke, heart failure, and other serious conditions.

Antipsychotics for dementia associated with elevated risks of serious adverse outcomes

Antipsychotic use in people with dementia is associated with elevated risks of a wide range of serious adverse outcomes including stroke, blood clots, heart attack, heart failure, fracture, pneumonia, and acute kidney injury, compared with non-use, finds a study published by The BMJ today.

Experts recommend shortening the blanking period after atrial fibrillation ablation

New evidence-based research calls into question the conventional three-month blanking period immediately after atrial fibrillation (AF) ablation, when early occurrences of AF are thought not to predict long-term AF recurrence.

Research reveals high prevalence of abnormal heart rhythms in adults with congenital heart disease

Almost 1 in 5 adults with congenital heart disease living in Israel had or developed an abnormal heart rhythm/arrhythmia during a five-year study, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Treating gum disease during AFib blanking period could reduce recurrence risk

Study evaluates whether treating periodontitis during the blanking period after atrial fibrillation (AF) ablation reduces AF recurrence, revealing that comprehensive periodontal care may significantly diminish recurrence rates by addressing inflammation linked to periodontitis.

Periodontal treatment after heart rhythm ablation may reduce AFib recurrence

Treating gum disease in the 3-months after a procedure to correct an irregular heartbeat known as atrial fibrillation (AFib) may lower oral inflammation and may reduce AFib recurrence, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Preventive ventricular tachycardia ablation cuts down ICD shocks and hospitalizations

The first randomized trial to investigate preventive ablation of a potential arrhythmogenic substrate associated with coronary chronic total occlusion (CTO) in patients at high risk of ventricular arrhythmias (VAs) reduces the risk of appropriate implantable cardioverter-defibrillator (ICD) therapy and unplanned hospitalization in patients with no previously recorded VAs.

New research advocates genetic screening in early onset atrial fibrillation

Although the vast majority of clinicians do not view atrial fibrillation (AF) as a genetic disorder, a White Paper in the Canadian Journal of Cardiology, published by Elsevier, analyzes the current understanding of genetics and the role of genetic testing in AF and concludes there is an increasing appreciation that genetic culprits for potentially life-threatening ventricular cardiomyopathies and channelopathies may initially present with AF.
