Scientific Statement on Noninvasive Risk Stratification Techniques for Identifying Patients at Risk …

Despite advances in medical and surgical management, the prognosis of chronic heart
failure remains poor. Few patients with chronic heart failure can be considered to have a …

Downloaded from scores the need for risk stratification techniques to identify patients at high
risk for these events and effective interventions that can prevent or abort these events …

Background—Risk stratification by means of analysis of QT dispersion (QTD) in the 12-lead
surface ECG is under intense investigation in various patient populations. The aim of the …

Background—The role of QTc interval prolongation in heart failure remains poorly defined.
To better understand it, we analyzed the QTc interval duration in patients with heart failure …

Heart failure is the final common pathway of various cardiac pathologies and is associated
with sudden cardiac death, mostly caused by ventricular arrhythmias. In this paper we briefly …

Interlead variability of the QT interval in surface electrocardiogram (ECG), ie, QT dispersion,
reflects regional differences in ventricular recovery time, and it has been linked to the …

When compared to the general population, patients with rheumatoid arthritis (RA) have an
overall standard mortality ratio of approximately two, with more than 50% of premature …

Background—QT dispersion is a potential prognostic marker of tachyarrhythmic events and
death, but it is unclear whether this applies to patients with congestive heart failure (CHF) …

Patients with heart failure are prone to a variety of arrhythmias, symptomatic and
asymptomatic, that are prognostically significant and have an important bearing on the …
