Sinus arrhythmia is the variation in heart rate attributable to respiration. Fox and Forges (1985) have found that the “amplitude” of sinus arrhythmia measured near birth is correlated with ...

Low concentrations of three selected biomarkers in the blood of patients with atrial fibrillation identify patients with a high chance of attaining sinus rhythm. This is the main result of this ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...
