Value of the Paced QRS Duration

Journal of Cardiac Failure, 2009
The value for paced QRS duration (pQRSd) to detect left ventricular (LV) dysfunction in right ventricular apex (RVA)-paced patients has not been evaluated.A total of 272 RVA-paced patients, including 99 with LV systolic dysfunction (LVSD) and 173 without LVSD, were enrolled in this study.

Prognostic Significance of Quantitative QRS Duration

American Journal of Medicine, 2006
Although QRS duration is known to be a predictor of mortality in patients with left ventricular dysfunction, our purpose was to evaluate the prognostic power of computer-measured QRS duration in a general medical population.Analyses were performed on the first electrocardiogram digitally recorded on 46,933 consecutive patients at the Palo Alto Veterans

Correction of the QRS duration for heart rate

Journal of Electrocardiology, 2019
To determine the clinical value of correcting the QRS duration for heart rate.We recently observed [1] that the QRS duration shortens during spontaneous increases in heart rate. In the current study, we analyzed ECG and pharmacokinetic data of 21 subjects who received quinidine in a recent study [2].

Assessment of QRS duration and presence of fragmented QRS in patients with Behçet’s disease

Coronary Artery Disease, 2013
QRS prolongation and the presence of QRS fragmentation in 12-lead ECG are associated with increased mortality and sudden cardiac death in the long term. In this study we aimed to assess QRS duration and fragmentation in patients with Behçet's disease (BD).A total of 50 patients (mean age 42.7±12.0 years) previously diagnosed with BD were recruited.
