Electrophysiology & Arrhythmia

 

Asymptomatic atrial fibrillation (AFib) patients could be at a heightened risk for cardiac complications, especially if the condition is paroxysmal, a study published in CHEST reports.

Artificial intelligence (AI)–assisted electrophysiology (EP) shows promise, but even its most ardent advocates aren’t ready for full-fledged endorsement—yet.   

The FDA issued a safety alert Jan. 17 for the Zoll LifeVest 4000, saying the external, wearable cardioverter defibrillator may fail to treat potentially fatal arrhythmias if it displays a specific error message which, by itself, doesn’t signal urgency.

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.

The document was released Wednesday at the 30th annual HRS scientific sessions in Boston.
