The relationship between gestational week and QT dispersion in cesarean section patients undergoing spinal anaesthesia: A prospective study

Background Pregnancy affects the cardiovascular system, particularly the cardiac conduction system, thereby increasing the susceptibility of patients towards arrhythmia. QT interval results in ventricular arrhythmias, predominantly polymorphic ventricular tachycardia. The present study was planned to investigate the relationship between a gestational week and QT dispersion in cesarean section patients undergoing spinal anaesthesia. Methods The study included 40 patients between the ages of 18 and 45 who had no symptoms of anaemia and undergoing elective cesarean section. The patients were separated into two groups based on the gestational week as Group I
