Key result
Radiofrequency catheter ablation effects on electrophysiologic parameters in AVNRT patients with modified slow pathways were investigated, though no quantitative results are reported in the abstract.
Why the study?
How does radiofrequency catheter ablation alter electrophysiologic parameters in patients with AVNRT who have persistent dual AV nodal physiology but no induction of AVNRT?
Observational
How does radiofrequency catheter ablation alter electrophysiologic parameters in patients with AVNRT who have persistent dual AV nodal physiology but no induction of AVNRT?
This study aims to elucidate the electrophysiologic mechanisms underlying the noninducibility of AVNRT after slow pathway modification in patients who still exhibit dual AV nodal physiology.
May clarify mechanisms of noninducibility despite persistent dual physiology; hypothesis-generating and requires prospective validation.
Background and Objectives: In cases of radiofrequency catheter ablation (RFCA) for patients with atrioventricular nodal re-entrant tachycardia (AVNRT), complete elimination of slow pathway is not always achievable. Furthermore, in situations of the so-called modified slow pathway, the underlying mechanism of tachycardia elimination remains unclear. Subjects and Methods: Patients who underwent RFCA for AVNRT, and showed persistence of dual atrioventricular nodal physiology but no induction of AVNRT after ablation were enrolled. We measured electrophysiologic parameters before and after the ablation procedure.

Kim et al. (2016) conducted an observational in AV Nodal Re-entrant Tachycardia (AVNRT). Radiofrequency catheter ablation (RFCA) vs. Before ablation was evaluated on Electrophysiologic parameters. Radiofrequency catheter ablation effects on electrophysiologic parameters in AVNRT patients with modified slow pathways were investigated, though no quantitative results are reported in the abstract.
