Context Hospitalization for heart failure is associated with high postdischarge mortality and
morbidity. The predictive value of the QRS duration during admission for heart failure has …

Adverse outcomes in heart failure occur more frequently with QRS prolongation. The results
of our study have shown that 1/4 of community hospital patients with heart failure of sufficient …

Background and Objectives It has been suggested that prolongation of the QRS duration (>
120 ms) is an independent risk factor for mortality in patients with cardiomyopathy. The …

Study objectives There is a lack of epidemiologic information about duration of QRS
complex in the general heart failure population. We sought to describe age, sex, and clinical …

Aims The independent clinical correlates and prognostic impact of QRS prolongation in
heart failure (HF) with reduced and preserved ejection fraction (EF) are poorly understood …

Background: Abnormal prolongation of QRS duration is a common finding in patients with
chronic heart failure, and is associated with an impaired prognosis. The optimum QRS …

BACKGROUND: Prolongation of the QRS duration has been shown to be associated with
adverse outcomes among heart failure (HF) patients. The association of QRS duration with …

BACKGROUND: This study investigated whether QRS duration (QRS D) is a prognostic
indicator in patients with heart failure (New York Heart Association [NYHA] classes II-IV) …

Background: Patients resuscitated from ventricular tachyarrhythmias benefit from
implantable cardioverter-defibrillators (ICDs) as opposed to medical treatment. Patients with …

Objectives: This study examined the relationship between baseline QRS duration and
clinical outcomes in subjects enrolled in the TOPCAT (Treatment of Preserved Cardiac …
