Implication

Supports conservative management without routine EPS in asymptomatic WPW; leaves open need for better risk-stratification tools.

Key Points

To determine the prognostic value of invasive electrophysiology testing in asymptomatic patients presenting with the Wolff-Parkinson-White electrocardiographic pattern.
Prospective study of 75 asymptomatic patients (aged 7–77 years, mean 34 ± 14 years; 44 male, 31 female) undergoing baseline electrophysiology testing.
Patients were followed annually for a median duration of 4.3 years, totaling 348 patient-years of follow-up.
Zero patients died suddenly, while 6 of 75 patients (8%) developed documented symptomatic supraventricular tachycardia during a median follow-up of 4.3 years.
Induction of reciprocating tachycardia during electrophysiology testing did not predict subsequent symptoms, whereas no patient lacking retrograde pathway conduction became symptomatic.
Loss of preexcitation occurred in 9 patients and was independently predicted by age (RR, 1.4 per decade; 95% CI, 1.0–1.8) and anterograde pathway refractory period (RR, 1.06 per 10 msec; 95% CI, 1.0–1.12).

Structured PICO

Does electrophysiology testing predict sudden death or symptomatic supraventricular tachycardia in asymptomatic patients with Wolff-Parkinson-White pattern?

Population

Asymptomatic patients with the Wolff-Parkinson-White electrocardiographic pattern

Intervention

Electrophysiology testing

Outcome

Sudden death and development of symptomatic supraventricular tachycardiahard clinical

In asymptomatic patients with Wolff-Parkinson-White pattern, the risk of sudden death is extremely low, and routine electrophysiology testing parameters like inducible tachycardia do not reliably predict future symptomatic arrhythmias.
