In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...

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 ...

The benefit of biventricular pacing in appropriate patients with congestive heart failure (CHF) now has been established in terms of both morbidity and mortality. [1,2,3,4,5] Current criteria for ...

The BLOCK HF trial demonstrated that, during continual cardiac pacing, adverse left ventricular remodelling and deterioration of systolic function occurred more frequently with right ventricular than ...

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

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 ...
