Voltage gradient mapping and electrophysiologically guided cryoablation in children with AVNRT

ConclusionsVoltage gradient mapping of Koch ’s triangle, combined with the search for the slow potential signal in low-voltage bridges, is effective in guiding cryoablation of AVNRT in paediatric patients, with a complete acute success rate and no AVNRT recurrences at mid-term follow-up.
