Arms Assigned Interventions
Rhythmia Mapping System & Catheter
This is a single arm diagnostic feasibility study with the Rhythmia Mapping System and the Rhythmia Mapping Catheter
Device: Rhythmia Mapping System and the Rhythmia Mapping Catheter
Patients will undergo a diagnostic assessment with the Rhythmia Mapping System and the Rhythmia Mapping Catheter as part of the Electrophysiology Ablation Procedure.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patient understands the implications of participating in the study and provides informed consent
  2. Patient is willing to comply with specified follow-up evaluation and can be contacted by telephone
  3. Patients referred for a catheter ablation procedure to treat an atrial or ventricular arrhythmia
  4. Patient can be heparinized during the procedure

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.)
