This is a retrospective, multi center clinical study collecting existing, de-identified subject data from medical records to be analyzed using an independent core laboratory to validate performance of a computational ECG mapping system (vMap™).

Official Title

Clinical Validation of the Vektor Computational ECG Mapping System (vMap™) for Atrial and Ventricular Arrhythmias/Pacing


Cardiac Arrhythmia Atrial Fibrillation Ventricular Arrythmia Premature Ventricular Complexes Multiple Ventricular Tachycardia Ventricular Fibrillation Premature Atrial Complex Atrioventricular Reentrant Tachycardia Premature Birth Arrhythmias, Cardiac Tachycardia Tachycardia, Ventricular Ventricular Premature Complexes Atrial Premature Complexes Cardiac ablation procedure

Open to people ages 22-100

  1. Patient has one of the following clinical arrhythmia/pacing types:
  2. Atrial pacing
  3. Atrial fibrillation
  4. Ventricular pacing
  5. Premature ventricular complex
  6. Ventricular tachycardia
  7. Ventricular fibrillation
  8. Focal atrial tachycardia
  9. Premature atrial complex
  10. Atrioventricular reentrant tachycardia
  11. Patient has undergone 'successful' routine, standard of care diagnostic electrophysiology (EP) study using intracardiac catheters as clinically indicated, guided by fluoroscopy and routine electroanatomic mapping, intracardiac echocardiography, and/or cardiac imaging such as CT or MRI.
  12. Patient has 12 lead electrogram data of clinical rhythms recorded on electrogram recording system.
  13. Patient has undergone a successful ablation procedure.
  14. Arrhythmia type and atrial/ventricular characteristics can be abstracted from patient medical records.
  15. Patient was between 22 and 100 years of age at time of EP study and ablation procedure.

You CAN'T join if...

Patients with unstable coronary artery disease, confirmed intracardiac thrombus, active sepsis, complex congenital heart disease, dextrocardia, severe pulmonary hypertension, decompensated heart failure, a mechanical heart valve, myocardial infarction within 1 month of ablation, inability to induce arrhythmia, unacceptable ECG data quality, and/or data included in the device training dataset.
