Effect of risk stratification on cost-effectiveness of the implantable cardioverter defibrillator.

abstract：OBJECTIVES:Impedance monitoring has been proposed as a method to assess the adequacy of tissue heating during catheter ablation procedures. The purpose of this study was to evaluate the relation among initial impedance, fall in impedance, and electrode temperature during catheter ablation procedures. METHODS AND RESUL...
