title: The relationship between QT dispersion and exaggerated blood pressure response to exercise stress testing.
abstract: This study was aimed to investigate sensitivity and specificity of QT dispersion (QTd) as a predictor of hypertensive response to peak exercise stress testing (EST). Fifty-nine patients were divided in to two groups (32 patients with exaggerated blood pressure response (EBPR) to EST group and 27 patients for normotensive group) and the EST was monitored. The QTd and corrected QT (QTc) intervals were still found to be significant predictors of EBPR (P < 0.05). In receiver operating characteristic (ROC) analysis, a level of QTd ≥ 40 predicted EBPR with 84% sensitivity and 74% specificity. According to the present data, QTd might be an important predictive marker for EBPR.
