Background and Purpose Automated measurements of electrocardiographic (ECG) intervals
are widely used by clinicians for individual patient diagnosis and by investigators in …

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—Prolonged duration of QRS complex in a 12-lead ECG is associated with
adverse prognosis in patients with cardiac disease, but its significance is not well …

QRS duration and morphology, evaluated via a standard 12-lead electrocardiogram (ECG),
represent an opportunity to derive useful prognostic information regarding the risk of …

Prolongation of QRS duration in electrocardiogram is one of the risk factors for morbidity and
mortality in many kinds of cardiac diseases. However, its molecular mechanism is unknown …

The QRS complex has been shown to be a prognostic marker in coronary artery disease.
However, the changes in QRS duration over time, and its predictive value for cardiovascular …

The objective of this study was to determine the combination of left ventricular ejection
fraction (LVEF) and individual electrocardiographic parameters related to abnormal …

Background: Permanent pacemaker (PPM) implantation has been identified as a risk factor
for morbidity and mortality after Fontan operation. This study investigated the factors …

Background: Prolonged QRS duration (pQRSd) on electrocardiogram (ECG) is a strong
predictor of poor outcome in heart failure, myocardial infarction, and myocarditis, but it is …

Background Cardiac death is one of the leading causes of death and sudden cardiac death
(SCD) is estimated to cause approximately 50% of cardiac deaths. Men have a higher …
