Key result
Positive intraoperative electrophysiological provocative testing strongly predicts postablative AF, enabling ~94% predictive accuracy.

A mathematical model incorporating clinical, instrumental, and electrophysiological predictors, including a modified intraoperative electrophysiological test, was developed to forecast postablative atrial fibrillation in patients with typical atrial flutter.
The article represents clinical, instrumental and electrophysiological predictors of postablative atrial fi brillation (AF) occurrence after radiofrequency ablation of cavotricuspid isthmus in 209 patients with typical atrial fl utter. The results of our own experience in the treatment of these patients are analyzed. The technique of the modifi ed intraoperative electrophysiological test of AF induction in patients with typical atrial fl utter is described. The role of this technique in the occurrence of postablative AF is evaluated. A mathematical model for predicting postablative AF at the intraoperative stage of treatment of patients with typical atrial fl utter has been developed.

Emel’yanenko et al. (2021) conducted an observational in Typical atrial flutter (n=209). Positive intraoperative electrophysiological provocative test vs. Negative test / absence of risk factors was evaluated on Occurrence of postablative atrial fibrillation (Cramer's V 0.7, p=<0.0001). A positive intraoperative electrophysiological provocative test was strongly associated with the development of postablative atrial fibrillation (p<0.0001), enabling a predictive model with 94% accuracy.
