SUDDEN death in persons with artificial pacemakers is a continuing and disturbing problem. Causes include pacemaker-catheter displacement, electric-component failure, broken wires and rising pacing ...

The rhythm is regular at a rate of 78 beats/min. Before each QRS complex, there are two pacing stimuli (+,v) with a very short interval (0.06 sec) between them. They are both ventricular pacing ...

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 ...

Ventricular arrhythmia occurs when the heart’s lower chambers beat out of sync, which can prevent the heart from effectively pumping blood throughout the body. Diagnosis of ventricular arrhythmia ...

Sinus node disease (SND), a common indication to implant a pacemaker, is associated with atrial tachyarrhythmias, specifically atrial fibrillation (AF), present either at implantation or detected ...

PHILADELPHIA — Accelerometer-based atrial sensing with a novel, enhanced, automated algorithm in patients with atrioventricular block and a single-chamber leadless pacemaker in the right ventricle ...

ICDs detect tachycardias imperfectly: An ICD-detected tachycardia may represent either a tachyarrhythmia (SVT or VT) or oversensing of nonarrhythmic electrical signals. ICDs also classify tachycardias ...

EnRhythm(TM) pacemaker and EnTrust(TM) defibrillators now available in Europe Medtronic, Inc. (NYSE:MDT) today announced the European introductions of the Medtronic EnRhythm(TM) pacemaker ...

Currently under review at the FDA, Abbott’s miniaturized, leadless pacemaker has aced a clinical study by showing it could speed up the beat of a patient’s heart once its rhythm falls out of sync. The ...
