Randomized Controlled Trial Multicenter Study
Effects of a rate smoothing algorithm for prevention of ventricular arrhythmias: results of the Ventricular Arrhythmia Suppression Trial (VAST).
Rate smoothing, which is available in some pacemakers and implantable cardioverter defibrillators (ICDs), has been used to prevent Torsades de Pointes in patients with long QT syndrome. Its efficacy in general ventricular arrhythmia prevention has not been determined. ⋯ Rate smoothing does not result in a reduction in ventricular arrhythmias in a heterogeneous population of patients receiving ICDs.

Multicenter Study
Factors associated with poor survival in women experiencing cardiac arrest in a rural setting.
The purpose of this study was to determine whether gender differences exist in the characteristics and outcomes for out-of-hospital cardiac arrest (OHCA) occurring in a rural setting. ⋯ In a rural population, women suffering OHCA have a dismal survival rate likely because of multiple unfavorable arrest characteristics.
