Key result
Radiofrequency ablation for frequent premature ventricular complexes significantly altered the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio compared to baseline (all p < 0.001).
Why the study?
Does radiofrequency ablation improve Tp-e interval and Tp-e/QT ratio in patients with symptomatic frequent premature ventricular complexes?
Population
151 consecutive patients with symptomatic frequent premature ventricular complexes (PVCs)
Comparison
Radiofrequency ablation (RFA) vs Pre-procedural baseline (before RFA)
Design
Cohort

Ablation-linked repolarization shifts in frequent PVCs are hypothesis-generating; randomized trials required before practice change.

Does radiofrequency ablation improve Tp-e interval and Tp-e/QT ratio in patients with symptomatic frequent premature ventricular complexes?
p-value: p=<0.001
Radiofrequency ablation of frequent PVCs significantly improves markers of ventricular repolarization (Tp-e interval and Tp-e/QT ratio) and left ventricular ejection fraction.
Yayla et al. (2017) conducted an observational in Symptomatic frequent premature ventricular complexes (n=151). Radiofrequency ablation (RFA) vs. Before RFA (baseline) was evaluated on Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio (p=<0.001). Radiofrequency ablation for frequent premature ventricular complexes significantly altered the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio compared to baseline (all p < 0.001).
