Factors determining long-term maintenance of sinus rhythm after cardioversion of persistent atrial fibrillation.
Long-term maintenance of sinus rhythm (SR) after successful cardioversion (CV) of persistent atrial fibrillation (AF) carries a low risk of stroke and may avoid the risks associated with anticoagulation. ⋯ Left atrial area and left ventricular fractional shortening are the independent predictors of the maintenance of SR after successful CV in patients with persistent AF.

Patients with chronic heart failure (CHF) are characterised by an increased ventilatory response to exercise. The role of exercise ventilation in the risk stratification and evaluation of patients with CHF has not yet been established. ⋯ In patients with stable CHF simple exercise ventilation parameters may provide important clinical and prognostic information.
