If the ventricular pacing is originating in the right ventricle like a normal pacemaker, a left bundle branch morphology will be present. This occurs since the right ventricle is activated first ...

A New Pacemaker Algorithm for the Treatment of Atrial Fibrillation: Results of the Atrial Dynamic Overdrive Pacing Trial (ADOPT) Electrophysiologic Characteristics of the Spontaneous Onset and ...

The 338 enrolled patients resulted in a potential for 676 leads to be implanted. Of the 676 leads, implantation was abandoned in 8 leads (three patients with exclusion criteria, two patients with ...

Multifocal atrial tachycardia — or MAT — is a rhythm that frequently occurs in the setting of severe lung disease. MAT is characterized by three different P-wave morphologies within one 10 ...

Unlike traditional pacemakers, leadless devices are implanted into the heart through a minimally invasive procedure. This eliminates the need for cardiac leads and wires connecting the pacemaker ...
