Electroanatomical Mapping of Patients Undergoing Catheter Ablation Procedures Using Rhythmia Mapping System and Catheter

Exclusion Criteria

• •1. Patients requiring an emergency ablation procedure
• •2. Patients hemodynamically unstable
• •3. Patients with NYHA Class III or IV heart failure
• •4. Women who are pregnant or lactating
• •5. Patients having cardiac surgery within the past two months
• •6. Patients with Long QT Syndrome, Brugada Syndrome, or Torsade de Pointes
• •7. Patients with intracardiac thrombus, tumor, or other abnormality which precludes catheter introduction
• •8. Patients with acute myocardial infarction within 3 months
• •9. Patients awaiting cardiac transplantation
• •10. Patients enrolled in any other clinical study
• •11. Patients with an age \<18 or \>75 years
• •12. Patients with stable/unstable angina or ongoing myocardial ischemia
• •13. Patients with congenital heart disease (not including atrial septal defect (ASD) or patent foramen ovale (PFO) without a right to left shunt) where the underlying abnormality increases the risk of an ablative procedure
• •14. Patients with pulmonary hypertension (mean or systolic pulmonary artery (PA) pressure \> 50mm Hg on Doppler echo)
• •15. Patients with a left atrial diameter \> 55 mm
• •16. Patients with any arrhythmia currently being treated where the arrhythmia or the management may interfere with this study
• •17. Patients with active infection or sepsis
• •18. Patients with untreatable allergy to contrast media
• •19. Patients with a history of blood clotting (bleeding or thrombotic) abnormalities
• •20. Patients with any known sensitivities to heparin or warfarin
• •21. Patients with severe chronic obstructive pulmonary disease (COPD) (identified by a forced expiratory volume \[FEV1\] \<1)
• •22. Patients with severe co morbidity or poor general physical/mental health that, in the opinion of the investigator, will not allow the patient to be a good study candidate (i.e. other disease processes, mental capacity, substance abuse, shortened life expectance, etc.)
