Remote, radiofrequency was delivered at a site remote from the diastolic pathway identified by the non-contact system.
On exit, radiofrequency was delivered on the VT exit identified by the non-contact system.
Near diastolic pathway, radiofrequency was delivered near an incompletely identified diastolic pathway.
On diastolic pathway, radiofrequency was delivered by a catheter positioned, using the locator signal, on the diastolic pathway identified by the non-contact system.
χ2 analysis for all data p < 0.0001.
With respect to the “on diastolic pathway” row: *p < 0.0001; †p < 0.005.
