QT dispersion may serve as a measure of variability in ventricular recovery time and may be
a means of identifying patients at risk of arrhythmias and sudden death after acute …

Aims Atrial fibrillation (AF) is one of the commonest sustained arrhythmias in chronic heart
failure (CHF), although the prognostic implications of the presence of AF in CHF remain …

ADENOSINE is an endogenous nucleoside that is capable of causing atrioventricular nodal
conduction block in humans. Although the use of intravenous adenosine to terminate …

Key points • Previous studies have shown that atrial electrical properties are altered (remodelled)
by atrial fibrillation (AF) and that the recurrence of AF is high following remodelling. …

Background—Although atrial electrical remodeling has been studied extensively in animal
models, the reversibility of this phenomenon after termination of clinical atrial fibrillation (AF) …

Objectives: Although previous studies in dogs have indicated a minimal role for changes in I
K1 in the shortening of action potential duration (APD) associated with atrial fibrillation (AF), …

In a proportion of patients with left free wall accessory connections, preexcitation is apparent
only during atrial arrhythmias or atrial pacing (latent preexcitation). These patients may be …

The incidence and prevalence of atrial fibrillation (AF) are projected to increase significantly
worldwide, imposing a significant burden on healthcare resources. The disease itself is …

OBJECTIVE: Atrial fibrillation (AF) is a common complication aftercoronary artery bypass
grafting (CABG) operations, occurring in 5 to 40% ofcases. A number of studies have implicated …

We studied the dynamics of QT dispersion over the first few days of myocardial infarction and
during coronary angioplasty. Ten patients with anterior myocardial infarction and an equal …
