The aim of this thesis was to analyze the influence of methylprednisolone (MP) PT on ECG changes, mainly on QT interval, as prolonged QT interval may induce ventricular arrhythmias and to identify other risk factors (RF) for QT prolongation. Data were gained retrospectively from medical records of patients hospitalized at II. Internal Gastroenterology Clinic of University Hospital Hradec Králové. QT was corrected to QTc using Bazzet (QTcB) and Fridericia (QTcF) formula, QTc >450 ms (men) and QTc >460 ms (women) was considered prolonged. QTc changes before and after pulse therapy were determined as ∆QTc. 325 pulses of MP were administered to 277 patients (66,0 % women), ECG was available in 94,2 % (n=306 from 325). After PT there was significant ∆QTcF 14,6 ms (p <0,001) and ∆QTcB 5,6 ms (p <0,001)....
