Intra-atrial re-entrant tachycardia in congenital heart disease: types and relation of isthmus to atrial voltage

ConclusionIn our population with a high proportion of complex CHD, CTI-related IART was the most frequent mechanism, although non-CTI-related IART was present in 49% of patients (alone or with concomitant CTI-related IART). A cut-off voltage of 0.5  mV could identify 95.4% of the substrates in non-CTI-related IART.
