Synopsis: The purpose of this clinical study is to evaluate the clinical usage of the EnSite Precision™ Cardiac Mapping System and the new software in a variety of procedures and clinical settings. The system is approved for use worldwide, so there are no parts of this study that would be considered experimental.

In order to assess this new and improved system, the information and data coming from your procedure and follow-up period will be collected and analyzed. Your doctor will treat your heart rhythm disorder as per normal standard practice in your hospital. There will be no change to your ablation procedure; however, there might be a small change to your long-term follow-up. Depending on your doctor’s standard follow-up practice, you might be invited one or two times more for an in-clinic visit throughout the study follow-up period.

Information collected during the course of this study will include data about your overall heart condition, the catheter ablation procedure and how you do after the procedure. You will also be asked some questions about how you are feeling physically and emotionally.
