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).

Dual antithrombotic therapy reduces risk of major bleeding events in AFib patients undergoing PCI

Dual antithrombotic therapy combined with the blood thinner dabigatran and a P2Y inhibitor could be a more effective—and less risky—alternative to standard care in atrial fibrillation (AFib) patients undergoing percutaneous coronary intervention (PCI), a study published this month in the New England Journal of Medicine reports.

Abbott smartphone-compatible cardiac monitor gains FDA clearance

Abbott has received FDA clearance for its smartphone-compatible insertable cardiac monitor (ICM), the healthcare company announced Oct. 23. The device allows a patient to actively monitor his heart activity while giving physicians the ability to identify arrhythmias remotely.

Thyroid hormone levels tied to increased risk of AFib

Higher levels of thyroid hormone in the blood were associated with an increased risk of atrial fibrillation (AFib), even when the levels were within normal range, according to an analysis of 11 studies containing more than 30,000 people.

Icelandic researchers ID genetic variant that increases risk of AFib

Icelandic researchers have uncovered two novel genetic variants of atrial fibrillation (AFib), one of which could increase the risk of developing AFib for susceptible patients.

Drug reactions with NOACs in AFib patients could result in major bleeding problems

Patients prescribed non-vitamin K oral anticoagulants (NOACs) to manage symptoms of atrial fibrillation (AFib) could be at increased risk for major bleeding if they are taking certain common medications at the same time, a study published in the Journal of the American Medical Association states.
