Corrigendum to: European Cardiac Resynchronization Therapy Survey II: rationale and design.

The Cardiac Resynchronization Therapy (CRT) Survey II is a 6 months snapshot survey initiated by two ESC Associations, the European Heart Rhythm Association and the Heart Failure Association, which is designed to describe clinical practice regarding implantation of CRT devices in a broad sample of hospitals in 47 ESC member countries. The large volume of clinical and demographic data collected should reflect current patient selection, implantation, and follow-up practice and provide information relevant for assessing healthcare resource utilization in connection with CRT. The findings of this survey should permit representative benchmarking both nationally and internationally across Europe.
