Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Persistence rates better with dabigatran than warfarin

Although warfarin is widely used to prevent strokes in patients with atrial fibrillation (AF), previous research has found the discontinuation rate to be high. In a study published online Aug. 6 in Circulation: Cardiovascular Quality and Outcomes, researchers found that a newer drug, dabigatran, resulted in better persistence rates in patients newly diagnosed with nonvalvular AF.

eCardio announces the appointment of John H. Untereker as its president

eCardio Diagnostics, a leader in remote arrhythmia monitoring services, has promoted John H. Untereker to President, effective immediately. He will remain COO.

Anticoagulants: The Brave New World

Novel anticoagulants offer physicians a welcome option to warfarin for treating patients with atrial fibrillation who are at risk of stroke. But proceed with caution until more data accumulate.

Boston Scientific receives FDA 510(k) clearance for the Rhythmia™ Mapping System

Boston Scientific Corporation has received U.S. Food and Drug Administration (FDA) 510(k) clearance for the Rhythmia™ Mapping System, a next-generation 3D mapping and navigation solution for use in cardiac catheter ablations and other electrophysiology (EP) procedures to diagnose or treat a variety of conditions in which the heart beats abnormally.

European report tracks lead extractions from 46 countries

The European Heart Rhythm Association (EHRA) added lead extractions to its annual compendium on arrhythmia treatments. The EHRA White Book was released online June 23 on the European Society of Cardiology (ESC) website in conjunction with the launch of EHRA EUROPACE 2013 in Athens.

Behind the scenes in Eliquis drama

The June issue of Pharmaceuticals Monthly explores the delay in the approval of apixaban (Eliquis) by the FDA. “Apixaban shows how a review that seems, on its face, like it should be a quick and clean affair can become derailed by issues that, but for the agency’s own public disclosures post-approval, would never see the light of day,” according to the article.

Dare to differ: Team work, challenging vendors improves care, costs

ATLANTA—Improve quality, reduce cost. That’s often the goal, but less often the outcome. The leader of an integrated electrophysiology (EP) program shared a formula for achieving quality and savings June 13 at the Cardiovascular Service Line Symposium.

Heart Rhythm Society visits Capitol Hill to gain support for important legislation impacting the field of electrophysiology

Today, members of the Heart Rhythm Society (HRS) are visiting 35 congressional offices on Capitol Hill to raise visibility and support for two proposals: the “Medicare Program Integrity Improvement and Education Act” and the “Teaching Children to Save Lives Act.” HRS is advocating for the support of these two bills because both intend to deliver outcomes aligned with the Society’s mission to improve the care of patients by advancing research, education and optimal health care policies and standards.
