Electrophysiology & Arrhythmia

Electrocardiograms (ECG) acquired using a chest strap could be a quality alternative to traditional ECGs when used to diagnose atrial fibrillation (AF), researchers reported in the American Journal of Cardiology.

A study published Feb. 14 in the American Journal of Cardiology suggests obese patients with atrial fibrillation (AF) fare better in terms of mortality and stroke events than their non-obese counterparts—a finding that’s in line with the much-contested “obesity paradox."

Black Medicare beneficiaries with implanted cardiac devices (ICDs) face a lower risk of atrial fibrillation (AF) than their white counterparts, despite a higher overall burden of vascular risk factors and a greater risk of stroke, researchers reported Feb. 11 in the Journal of the American Heart Association.

His-optimized cardiac resynchronization therapy successfully narrowed QRS duration, improved left ventricular (LV) ejection fraction and heightened functionality in 27 patients with advanced heart failure (HF), according to a study published in Circulation: Arrhythmia and Electrophysiology.

The lifetime cumulative risk of sudden cardiac death (SCD) is much higher in black patients than in whites, according to an analysis of the Atherosclerosis Risk in Communities Study published in Circulation Feb. 4.

Researchers from the Thayer School of Engineering at Dartmouth College have developed a dime-sized innovation they claim converts the heart’s energy into electricity to power implantable devices like pacemakers and defibrillators, potentially saving cardiovascular patients the time, money and stress of repeat surgery.

Atrial fibrillation (AF) is rare during dobutamine stress echocardiography (DSE), a routine exam for assessing coronary ischemia, but elderly patients and those with a history of paroxysmal AF are at an increased risk for arrhythmia during the test, a team of researchers from Boulogne, France, reported.

A Journal of the American Heart Association study focused on the programming safety of cardiac implantable electronic devices (CIEDs) suggests the publication of clinically meaningful trial results and professional recommendations translates poorly into real-world practice, penetrating just a fraction of a field that might benefit from added guidance.

Stryker announced on Feb. 1 it is voluntarily recalling certain Lifepak 15 monitor/defibrillators over an issue which may cause the devices to lock up and not deliver potentially life-saving therapy. The company reported there have been six patient deaths after delays in therapy related to this problem.

Cancer patients who experienced tachycardia within one year of being diagnosed carried higher mortality rates up to a decade later—even after adjusting for clinical characteristics and medication use—according to research presented Jan. 25 at the Advancing the Cardiovascular Care of the Oncology Patient conference.

Breast cancer patients under 60 years old are nearly twice as likely as their healthy counterparts to develop both short- and long-term atrial fibrillation (AF), researchers reported Jan. 29 in Heart Rhythm.

Non-vitamin K oral anticoagulants (NOACs) including dabigatran, rivaroxaban, apixaban and edoxaban have replaced warfarin as the preferred treatment for reducing stroke risk in patients with atrial fibrillation, according to updated guidelines issued Jan. 28.
