Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: - Acceptance for catheter ablation of frequent PVC. - Pre-procedural 12-lead ECG documentation of PVCs with a suspected site of -origin in the right or left ventricular outflow tract based on the PVC morphology (right bundle branch of left bundle branch morphology and inferior axis) - Absence of structural heart disease (assessed by echocardiography).

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
- Site of ablation success (RVOT vs LVOT). - Local activation time during PVC at each pacing site - Percentage of pace-match correlation calculated by PASOTM software at each pacing site	—

Secondary

Measure	Time frame
- Presence/absence of reversed polarity at the site of ablation success - Secondary endpoint: Ablation success 3 months after the procedure, determined by Holter and defined as a reduction in PVC burden >80%	—
