Electrophysiology & Arrhythmia

A Stanford- and Apple-led atrial fibrillation study of more than 400,000 U.S. residents—the largest AFib screening effort to date—has entered its final phase of data collection, the company announced Nov. 1. The trial is expected to wrap up early next year.

An augmented reality (AR) technique involving 3D visualization of myocardial scar can assist physicians in evaluating and treating cardiac damage during electrophysiological interventions like ventricular tachycardia (VT) ablation, researchers reported in PLOS One.

Patricia V. Blake will take over as CEO of the Heart Rhythm Society (HRS) next March, HRS leadership announced Oct. 26.

Higher ejection fractions (EFs) among heart failure patients are associated with an increased incidence of atrial fibrillation (AF) and worse cardiovascular outcomes, according to data from a multinational European registry.

Medtronic co-founder Earl Bakken, who invented the world’s first wearable, battery-powered pacemaker, died on Oct. 21 in his Hawaii home, the company announced. He was 94.

Officials in Clark County, Indiana, are urging locals to download a new phone app that would alert CPR-certified individuals to cardiac arrests happening nearby. An accompanying app also maps out the county’s nearest automated external defibrillators.

Clinically significant arrhythmias are rare during exercise stress tests (ESTs) in pediatric heart patients, researchers reported in JACC: Clinical Electrophysiology, but those most at risk for life-threatening events can be identified from a set of predefined risk factors like cardiomyopathy and ventricular dysfunction.

Catheter ablation was associated with better arrhythmia-free survival and lower complication rates than surgical ablation in patients with paroxysmal or early-onset persistent atrial fibrillation (AFib), according to a small, randomized study published in Circulation: Arrhythmia and Electrophysiology.

A team at Purdue University in West Lafayette, Indiana, announced progress on its latest cardiology wearable: a plant-based, stretchable wrist sticker that has the ability to monitor physical activity and alert users to health risks in real-time.

Harvard Medical School scientists have created a wirelessly programmed, miniaturized pacemaker which functions for weeks to months at a time, opening the door to “previously impossible investigations of arrhythmia and heart failure in the mouse.”

Preliminary results from the RETAKO trial, a study of takotsubo syndrome (TTS) in the Spanish population, have identified cardiogenic shock as an independent, strong predictor of mortality and complexities in TTS patients—a demographic that’s already at considerable risk for complications.

Direct oral anticoagulants (DOACs) can cut the short-term risk of thromboembolic events in half for patients who have undergone cardioversion of atrial fibrillation (AFib), suggests a meta-analysis published in the Journal of the American College of Cardiology.
