Dr Amal Mattu discusses a recent study on using the modified Sgarbossa criteria for diagnosing acute coronary occlusion in the presence of a ventricular paced rhythm.

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 stabl ...

Main panel: Atrial and extended bipolar ventricular electrograms are shown with Marker Channels. The first two complexes show atrial-sensed, ventricular paced rhythm.

The first-ever pacemaker to include Managed Ventricular Pacing (MVP), the EnRhythm Pacing System promotes intrinsic conduction and is clinically proven to significantly reduce unnecessary right ...

This review highlights new developments in cardiac implantable electronic devices, with an emphasis on pacemakers, newer modes of pacing, and implantable cardioverter–defibrillators.

MARVEL 2 is an early study looking at use of the leadless Micra ventricular pacemaker to provide atrioventricular synchronous pacing in patients with normal sinus rhythm. The authors demonstrate ...

Therapies are delivered in the form of anti-tachycardia pacing (ATP) or shocks to convert to sinus rhythm from sustained ventricular tachycardia or ventricular fibrillation, both of which are life ...

The heart has upper chambers -- the atrium -- and bottom chambers -- the ventricles. And, the different types of arrhythmias can originate in one of those different chambers. So when an arrhythmia ...

At rest, a healthy heart maintains a steady rhythm between 60 and 100 beats per minute. This rhythm begins in the right atrium at the sinoatrial node, often called the natural pacemaker of the heart.

The EnRhythm pacemaker is an ideal pacemaker for patients who have an abnormally slow or weak heart rhythm (bradycardia) due to sinus node dysfunction or intermittent AV block.
