Background: The epidemiology and clinical implications of asymptomatic atrial tachyarrhythmias (AT) including both atrial fibrillation and flutter in pacemaker recipients with and without arrhythmia ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

Pacemakers identify atrial fibrillation and enable initiation of anticoagulation to prevent strokes, according to new research. "Atrial fibrillation (AF) is the most common heart rhythm disorder and ...

A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable ...

Clinical trials and studies with ivabradine implicate cardiac pacemaker channels (HCN4) in the pathogenesis of atrial arrhythmias. Because acute changes in cardiac autonomic tone predispose to atrial ...

The sinoatrial node or simply sinus node (SN), atrioventricular node (AVN) and His- Purkinje network constitute the cardiac conduction system and are responsible for the initiation and coordinated ...

St Paul, MN -St Jude Medical has received FDA approval to distribute a new version of its 3500/3510 programmer software that will access the atrial fibrillation (AF) suppression feature in two of its ...

The Aveir DR dual-chamber leadless pacemaker system (Abbott) performs well out to 1 year in patients largely treated for sinus node dysfunction or atrioventricular (AV) block, according to extended ...

This story is part of a series on the current progression in Regenerative Medicine. This piece discusses the regeneration of the cardiovascular system. In 1999, I defined regenerative medicine as the ...

Researchers at the University of Manchester and Manchester University NHS Foundation Trust have discovered a backup natural pacemaker, which is able to generate a pulse and control the heart rate. The ...

NEW ORLEANS -- A leadless dual-chamber pacemaker with bidirectional wireless communication turned in very promising short-term results in patients with standard indications for dual-chamber pacing, ...
