    Intra-procedural atrial tachycardia (IAT) occurred in 13.33% of patients undergoing RFCA for paroxysmal atrial fibrillation (PAF).

  • 2

    Right atrial enlargement was identified as an independent risk factor for IAT, with an odds ratio of 1.14 (P = 0.015).

  • 3

    The primary mechanisms of IAT involved macro-reentrant circuits around the tricuspid and mitral annuli, with various subtypes identified.

  • 4

    The 12-month sinus rhythm maintenance rate was similar between IAT and non-IAT groups, at 78.0% overall (P = 0.84).

  • 5

    Successful intra-procedural identification and targeted ablation of IAT can lead to comparable long-term outcomes as in non-IAT patients.
