Evaluation of Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in patients with acute pancreatitis

Aim: Acute pancreatitis may affect cardiovascular system regardless of etiology. Electrocardiographic parameters such as QT interval, corrected QT interval (QTc), Tp-e interval and Tp-e/QT, Tp-e/QTc ratio can be used to evaluate myocardial repolarization. We aimed to investigate the effects of acute pancreatitis on the cardiovascular system and the relationship between ventricular repolarization parameters and the severity of the disease.Methods: Ventricular repolarization parameters (QT interval, QTc interval, Tp-e/QT, Tp-e/QTc ratio) of the patients who were included in the study and diagnosed with acute pancreatitis were compared with the control group patients. In addition, these parameters and Ranson, APACHE II and amylase values were taken into account in all patients in the pancreatitis group and the relationship between the severity of the disease and cardiac parameters was investigated.Results: 60 patients (30 acute pancreatitis and 30 control) were examined. Tp-e interval, Tp-e/QT and Tp-e/QTc ratios were significantly higher in the acute pancreatitis group compared to the control. In addition, Tp-e interval, Tp-e/QT and Tp-e/QTc ratios showed a positive correlation with the Ranson and APACHE II scores and Tp-e interval displayed a positive correlation with amylase levels.Conclusions: Tp-e interval, Tp-e/QT and Tp-e/QTc ratios can be used as a marker for the detection of ventricular arrhythmia risk in acute pancreatitis patients and Tp-e/QT and Tp-e/QTc ratios increased depending on the severity of AP and Tp-e interval increased in parallel with higher levels of amylase. Amylase level alone could be an indicator for increased risk of ventricular arrhythmia in patients with acute pancreatitis.
