BACKGROUND Nearly 40% of patients with long QT syndrome (LQTS) can have a nondiagnostic QTc at rest. Treadmill and cycle exercise stress testing are used in the diagnostic evaluation of LQTS. OBJECTIVE The purpose of this study was to determine the diagnostic significance of peak exercise and recovery phase QTc values during treadmill stress testing in LQTS. METHODS An Institutional Review Board-approved, retrospective analysis was performed on the treadmill stress tests in 243 patients… CONTINUE READING
