Electrophysiology & Arrhythmia

 

Patients with atrial fibrillation (AFib) who are admitted to rural hospitals have a 17 percent increased risk of death during their stay compared to those admitted to urban facilities, researchers reported in HeartRhythm.

Recent research provided sobering news on Americans’ ability to respond to cardiac arrest, which has about a 10 percent survival rate when occurring outside the hospital, according to the American Heart Association (AHA).

Patients with single-chamber (VVI) implantable cardioverter-defibrillators (ICDs) programmed with longer intervals for detecting arrhythmias experienced significant reductions in appropriate therapies, shocks and all-cause mortality when compared to patients with standardly programmed ICDs, according to a study published online Nov. 20 in JACC: Clinical Electrophysiology.

The incidence of young athletes experiencing sudden cardiac arrest during competitive sporting events is slim—just 0.76 cases in 100,000 athlete-years—but it does happen, according to one team of Canadian researchers who analyzed dozens of out-of-hospital cardiac arrests in an effort to dissect the underlying causes of these tragedies.

The first-ever proteome of the healthy human heart is complete, a team at the Technical University of Munich has reported—thanks to the successful logging of nearly 11,000 proteins and billions of cells.

iRhythm, Stanford Machine Learning create comprehensive cardiac arrhythmia detection algorithm

In a collaboration between digital healthcare company iRhythm and the Stanford Machine Learning Group (SMLG), an algorithm has been developed to detect 14 different cardiac output classes, including 12 arrhythmias.

Breast implants could skew ECG results

New research from Monaco suggests that breast implants can impede electrocardiogram (ECG) recordings, leading to false readings and potentially incorrect heart attack diagnoses.

Extended exposure to airport noise may increase risk of stroke, heart flutter

Living near an airport may make for a quick commute when getting out of town, but that convenience may come at a cost. New research suggests such an environment, with long-term exposure to aircraft noise throughout the day, may increase risk of hypertension, heart flutter and stroke.

New wireless, battery-free pacemaker is powered by microwaves

Researchers from Rice University and the Texas Heart Institute are introducing a wireless pacemaker that can be implanted directly into a patient’s heart at this week's IEEE’s International Microwave Symposium in Honolulu, running through June 9.

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’s Zio monitor shows superiority in detecting AFib over Holter devices

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).
