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 ...

Recently, cardiac resynchoronization has been proposed as long-term treatment for patients with severe heart failure despite optimal medical therapy. This electrical strategy is currently offered to ...

This Journal feature begins with a case vignette that includes a therapeutic recommendation. A discussion of the clinical problem and the mechanism of benefit of this form of therapy follows. Major ...

Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function. In this study, we examined whether biventricular pacing is ...

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 and ...

Patients with indications for cardiac resynchronization therapy (CRT) have better clinical outcomes when they undergo left bundle branch area pacing (LBBAP) rather than conventional biventricular ...

When a heart patient with an implanted pacemakerundergoes electrocardiogram testing,the cardiologist must be able to detect thepresence and effects of the pacemaker (seesidebar, “When the heart’s ...

Researchers at Texas Heart Institute (THI) and UCLA crossed a significant milestone in the development of wirelessly powered, leadless pacemakers. In an article in the Nature Research journal ...
