Abstract

Objectives: To evaluate exercise stress test (EST) as a risk stratification tool in asymptomatic Wolff-Parkinson-White (WPW) patients, through determining the correlation between EST and electrophysiology study (EPS). Subjects and methods: 35 asymptomatic WPW patients were risk stratificated via EST; thereafter the subjects underwent EPS. Data collected from both tests was analyzed to detect the correlation.Sensitivity, specificity, positive (PPV), and negative predictive value (NPV) of EST to risk stratificate was calculated. Results: 34 patients completed EST as their heart rate achieved expectation, one patient postponed EST due to an tachycardia, 6 subjects were stratificated as low risk via EST. EPS classified 10 patients as high risk; in 7 of the 10 subjects, Atrioventricular Reentry Tachycardias (AVRTs) were induced. Compared to EPS, The sensitivity, specificity, PPV, and NPV of EST to risk strafiticateasymptomatic WPW patients was 90%, 20%, 31.1%, and 83.3%, respectively. Conclusions: EST is feasible for risk stratificating in asymptomatic WPW patients; the test shows high sensivity and NPV, low specificity and PPV.
