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

Inclusion criteria

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

Exclusion criteria

• Patients requiring an emergency ablation procedure
• Patients hemodynamically unstable
• Patients with NYHA Class III or IV heart failure
• Women who are pregnant or lactating
• Patients having cardiac surgery within the past two months
• Patients with Long QT Syndrome, Brugada Syndrome, or Torsade de Pointes
• Patients with intracardiac thrombus, tumor, or other abnormality which precludes catheter introduction
• Patients with acute myocardial infarction within 3 months
• Patients awaiting cardiac transplantation
• Patients enrolled in any other clinical study
• Patients with an age <18 or >75 years
• Patients with stable/unstable angina or ongoing myocardial ischemia
• 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
• Patients with pulmonary hypertension (mean or systolic pulmonary artery (PA) pressure > 50mm Hg on Doppler echo)
• Patients with a left atrial diameter > 55 mm
• Patients with any arrhythmia currently being treated where the arrhythmia or the management may interfere with this study
• Patients with active infection or sepsis
• Patients with untreatable allergy to contrast media
• Patients with a history of blood clotting (bleeding or thrombotic) abnormalities
• Patients with any known sensitivities to heparin or warfarin
• Patients with severe chronic obstructive pulmonary disease (COPD) (identified by a forced expiratory volume [FEV1] <1)
• 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.)
