Case in brief
A 12-year-old male athlete was referred for asymptomatic pre-excitation found on a routine electrocardiogram. Pre-excitation persisted during exercise testing up to maximum heart rate. Electrophysiologic study identified a fasciculoventricular pathway (FVP), with no inducible arrhythmia. Ablation was not attempted, and he was discharged with unrestricted return-to-play authorization.
What made this case unusual
Persistent pre-excitation at maximum heart rate was evaluated electrophysiologically and attributed to an FVP rather than a more common accessory pathway.
Diagnostic / clinical pearl
In an asymptomatic patient with pre-excitation, electrophysiologic evaluation can identify an FVP and help avoid unnecessary ablation or exercise restriction.
Why it matters
FVPs are not substrates for re-entrant tachycardia and are not associated with sudden death, according to the report.
