Key result
Transesophageal electrophysiological study at 9 mV successfully stratifies preexcitation syndrome risk without inducing AF.
Why the study?
Risk stratification is recommended for symptomatic patients with preexcitation syndrome, but transesophageal electrophysiological study (TEEPS) has not become routine due to historical hardware and method limitations.
Population
One 19-year-old man with preexcitation syndrome presenting with palpitations and fatigue

May support safer TEEPS risk stratification in preexcitation; hypothesis-generating from single case, needs prospective validation.

Improved transesophageal electrophysiological study (TEEPS) using low pacing voltage offers a simple, safe, and reliable non-invasive method for risk stratification in patients with preexcitation syndrome.
Qin et al. (2021) conducted a case report in Ventricular preexcitation syndrome (n=1). Improved transesophageal electrophysiological study (TEEPS) was evaluated. Improved transesophageal electrophysiological study using a pacing voltage of 9 mV successfully stratified the risk of a patient with preexcitation syndrome without inducing atrial fibrillation.
