Electrophysiology & Arrhythmia


Roughly 1 in 4 children with Brugada syndrome treated with implantable cardioverter-defibrillators (ICDs) received life-saving shock therapy in a single-center study of 35 patients published in the Journal of the American College of Cardiology. However, 20 percent experienced inappropriate shocks and another 14 percent had device-related complications, highlighting the challenging clinical decision-making in this high-risk group.

Analyzing the change in stroke risk factors for atrial fibrillation (AFib) patients was far more powerful in predicting stroke than assessing baseline risk factors alone, researchers reported in the Journal of the American College of Cardiology.

Longtime claims that heart patients fitted with implantable cardiac devices should forgo MRI testing for safety concerns could be incorrect and “outdated,” according to new research published in the New England Journal of Medicine.

When writing about a recent JAMA Cardiology study, I was struck by an image of former Loyola Marymount University basketball star Hank Gathers swinging from the rim after a powerful dunk—and then collapsing to the court seconds later. Gathers died at 23.

New technology developed at New York’s Binghamton University could change the way clinicians detect heart disease with MRI scans, research published in the journal Colloid and Surfaces B: Biointerfaces suggests.

Pacemaker Predicaments: Reining in Implantation Rates in Low-risk TAVR

The need for permanent pacemakers in patients with severe aortic stenosis who undergo transcatheter aortic valve replacement (TAVR) remains a complication, even as TAVR expands into lower-risk groups. That may prove to be a limitation, especially with younger patients who may have decades of life ahead of them.

An analysis conducted at the Munich Octoberfest found that acute alcohol consumption was associated with sinus tachycardia and other cardiac arrhythmias.

Patients with low health literacy may be less aware of their atrial fibrillation diagnosis

After adjusting for sociodemographics, health behaviors and clinical characteristics, patients with atrial fibrillation who had low health literacy were less likely to be aware of their diagnosis, according to an analysis of members from two large health insurance companies.

85% of atrial fibrillation patients receive inadequate anticoagulation prior to stroke

Nearly 85 percent of patients with a history of atrial fibrillation who had an acute ischemic stroke did not receive guideline-recommended anticoagulation or had anticoagulation levels that did not fall in the therapeutic range, according to a registry analysis.
