Randomized Controlled Trial Clinical Trial
Effect of rate and rhythm control on left ventricular function and cardiac dimensions in patients with persistent atrial fibrillation: results from the RAte Control versus Electrical Cardioversion for Persistent Atrial Fibrillation (RACE) study.
The purpose of this study was to evaluate left ventricular function and atrial and ventricular diameters in patients with persistent atrial fibrillation (AF) treated with rate or rhythm control. ⋯ Routine rate control prevents deterioration of left ventricular function. Maintenance of sinus rhythm is associated with improvement of left ventricular function and reduction of atrial sizes.

The purpose of this study was to evaluate a substrate-modifying, primarily potential-guided catheter ablation approach as a bailout therapy in patients with complex myocardial infarction and electrical storms due to ventricular tachycardias (VTs). ⋯ The cases presented demonstrate that rescue VT ablation of drug-refractory electrical storm is possible by a substrate-orientated ablation approach even in patients with complex chronic infarction and various VTs.
