The Tp\u2010e interval, Tp\u2010e\/QT ratio, and Tp\u2010e\/QTc ratio are also known as predictors of ventricular arrhythmogenesis. The aim of this study was to assess ventricular repolarization in patients with CSF by using Tp\u2010e interval, Tp\u2010e\/QT ratio, and Tp\u2010e\/QTc ratio.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study included 50 patients with CSF and 51 control subjects. Coronary flow rates of all subjects were documented by thrombolysis in myocardial infarction (TIMI) frame count (TFC). Tp\u2010e interval, Tp\u2010e\/QT ratio, and Tp\u2010e\/QTc ratio were measured from the 12\u2010lead electrocardiogram. These parameters were compared between groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In electrocardiographic parameters analysis, QT, QTc, QTd, and QTcd were significantly increased in CSF patients compared with the control subjects (P &lt; 0.001, P = 0.019, P &lt; 0.001, P &lt; 0.001, respectively). The Tp\u2010e interval, Tp\u2010e\/QT ratio, and Tp\u2010e\/QTc ratio in the CSF patients were significantly higher than those in the control subjects (Tp\u2010e: 117 \u00b1 21 milliseconds [ms] vs 96 \u00b1 16 ms, P &lt; 0.001; Tp\u2010e\/QT: 0.30 \u00b1 0.06 vs 0.27 \u00b1 0.06, P = 0.005; Tp\u2010e\/QTc: 0.27 \u00b1 0.06 vs 0.24 \u00b1 0.05, P &lt; 0.001). In the multivariate analysis, increased Tp\u2010e and Tp\u2010e\/QT ratio were associated with CSF.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study revealed that
