Electrophysiology & Arrhythmia


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.

From pocket-sized electrocardiograms to watches that measure blood glucose levels, the field of medical technology is rapidly evolving. But these innovations, though oftentimes successful, aren’t necessarily living up to what scientists want them to be, according to presenters at the American Heart Association’s Scientific Sessions 2017.

Men are more likely to receive bystander cardiopulmonary resuscitation (CPR) in public locations than women and are more likely to survive cardiac arrest in those situations, according to research presented Nov. 11 at the American Heart Association’s (AHA) scientific sessions in Anaheim, California.

A new left atrial appendage (LAA) closure device can be implanted with a high success rate and slashes the one-year risk of stroke in nonvalvular atrial fibrillation (NVAF) patients, according to the researchers of the device’s pilot trial.

More cardiac arrest victims will survive if emergency medical dispatchers give cardiopulmonary resuscitation (CPR) instructions over the phone and if infants and children receive rescue breaths in addition to chest compressions, according to updated CPR guidelines released Nov. 7 by the American Heart Association (AHA).

Mining the Gap: Researchers Dig for Data to Reduce Disparities in Atrial Fibrillation Treatment

Black people with atrial fibrillation (AF) experience vastly higher rates of serious coronary events, so it’s not surprising that a growing number of clinical studies are aggressively tackling the complex issues around the impact of race—as well as gender—on management and outcomes of the heart rhythm disorder.

Registry analysis finds most eligible adults receive a CRT-D device

Nearly 90 percent of adults who were eligible for cardiac resynchronization therapy defibrillators (CRT-D) were implanted with the device, according to a retrospective registry study.

CMS plans on finalizing proposal to cover leadless pacemakers

80% of older adults survive more than two years after ICD implantation

Nearly 80 percent of older adults who received an implantable cardioverter-defibrillator (ICD) survived at least two years, according to a registry analysis of Medicare beneficiaries.

Alcohol abuse may increase risk for atrial fibrillation, MI, congestive heart failure

After adjusting for multiple variables, adults who abused alcohol had increased risks of atrial fibrillation, MI and congestive heart failure, according to a longitudinal analysis. The relative risk for those outcomes were highest in adults who had no established cardiovascular risk factors.

Level of evidence in atrial fibrillation guidelines remains consistent from 2001 to 2014

Although the number of randomized trials evaluating atrial fibrillation increased by more than 200 percent from 2001 to 2014, there was no significant increase in the use of level A evidence used in guidelines.
