Arrhythmias

Ruxolitinib, a drug that is already approved by the U.S. Food and Drug Administration (FDA) for treating certain cancers and skin conditions, is effective at inhibiting CaMKII, a protein kinase linked to cardiac arrhythmias. In a new study…

A new study from University of Louisville researchers in the Christina Lee Brown Envirome Institute has found that exposure to e-cigarette aerosols can cause heart arrhythmias in animal models -- both in the form of premature and skipped…

Physician’s Briefing Staff MONDAY, Oct. 17, 2022 (HealthDay News) -- In susceptible children, electronic gaming can precipitate lethal cardiac arrhythmias, according to research published online Oct. 10…

Physician’s Briefing Staff WEDNESDAY, Sept. 14, 2022 (HealthDay News) -- For adolescents, exposure to fine particulate matter (fine particles with aerodynamic diameters ≤2.5 µm ) is associated with an…

Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers at the Georgia Institute of Technology and clinicians at Emory…

A spiral wave of electrical activity in the heart can cause catastrophic consequences. One spiral wave creates tachycardia -- a heart rate that's too fast -- and multiple spirals cause a state of disorganized contraction known as…

Researchers make a compelling, evidence-based case for expanding the diagnostic workup to include cardiac arrhythmias when a normally continent individual experiences enuresis nocturna (involuntary urination during sleep). Their…

The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart's rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study co-led by researchers at Weill Cornell Medicine,…

Implantable cardiac monitoring (ICM) turned up a substantial burden of serious arrhythmic events in high-risk patients after a heart attack, despite not meeting conventional ejection…

An SGLT2 inhibitor seemed to offer protection from reduced ventricular arrhythmias in heart failure patients, according to a post hoc analysis of DAPA-HF. In that trial, the cohort…
