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patients fitted with implantable cardiac devices should forgo MRI testing for safety concerns could be incorrect and “outdated,” according to new research published in the New England Journal of Medicine.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

Here’s how heart rate could influence why men are more prone to criminal activity

A new study by researchers at the University of Pennsylvania produced evidence that shows men’s lower resting heart rate could contribute to why they commit crimes at a higher rate.

Eating chocolate regularly could reduce chances of AFib

There’s nothing wrong with indulging in chocolate regularly—at least when it comes to your heart, according to a new study.

Lean body mass—not obesity—predominant risk factor for AFib

Newly published research examined 3,868 atrial fibrillation (AFib) outcomes collected from the Danish Diet, Cancer and Health Study. Led by Morten Fenger-Grøn, MSc, with Aarhus University in Denmark, the study found no association between risk factors and obesity-related measurements, rather identifying lean body mass as the predominant driver of risk for AFib

iRhythm Technologies, which specializes in digital cardiac care, presented encouraging results from a study on its Zio continuous ambulatory monitoring system that showed it is more efficient in detecting arrhythmias than competitors' monitors.

HRS2017: Wearable defibrillators are safe, effective for pediatric patients

A new study from Cincinnati’s Children’s Hospital has found that the use of a wearable cardioverter defibrillator (WCD) is safe and effective for treating ventricular arrhythmias in pediatric patients at risk from sudden cardiac death.

HRS2017: AI-enabled Apple Watch detects AFib in UCSF study

Apple devices just keep getting smarter. New research presented at this year’s Heart Rhythm Society (HRS) conference in Chicago showed that when paired with an artificial intelligence-based algorithm, the watch can detect atrial fibrillation (AFib). 

HRS2017: Easy-to-use nasal spray first to treat tachycardia condition

Though physicians typically use adenosine, calcium channel blockers or beta-blockers in patients suffering from paroxysmal supraventricular tachycardia (PSVT), new research has given evidence that a simple, self-use nasal spray could be effective, too.

4-lead phone-based ECG could improve cardiovascular diagnostics in low-income countries
