Wolff–Parkinson–White syndrome: a single exercise stress test might be misleading

Abstract

AbstractRisk stratification of patients with Wolff–Parkinson–White syndrome for sudden death is a complex process, particularly in understanding the utility of the repeat exercise stress test. We report a case of an 18-year-old patient who was found to have a high-risk pathway by both invasive and exercise stress testing after an initial exercise stress test showing beat-to-beat loss of pre-excitation.
