Abstract:
Objective:This study aimed to investigate the changes of ventricular repolarization index on ECG and its relationship between prognosis in patients with acute cerebral trauma.Methods:From January 2014 to January 2018, data of 289 consecutive patients with emergency traumatic brain injuries were prospectively collected and ultimately 219 cases were selected into the study group. Meanwhile, 220 healthy persons matched by age and sex served as the control group. ECG indexes such as P wave dispersion (Pd), corrected QT(QTc), Tp-e and Tp-e/QT were all measured and calculated in the 1st and 72th hour. The independent sample t test and paired t test were used to compare the changes of the above indexes on the 1st day and the control group, the 1st day and the 3rd day, respectively, and the association between ECG indexes and the illness severity or adverse events (MACE) of the trauma group during hospitalization. Results:QTc, Tpec and Tp-e/QT of the acute cerebral trauma group increased on the 3rd day compared with the control group and on the first day, the differences were statistically significant ( P all <0.05). Tp-ec and Tp-e/QT in patients with moderate to severe brain injury in Glasgow Coma Scale (GCS) were increased, and the differences were statistically significant (150.48±16.58 vs 130.14±11.86, P=0.006). 0.29±0.04 vs 0.23±0.03, P=0.030). Tpec and Tp-e/QT were significantly increased in acute brain truma patients with MACE during hospitalization compared with those without MACE (149.76±12.52 vs 128.84±12.47, P <0.001). 0.30±0.04 vs 0.21±0.03,<0.001). Conclusion:Tp-e and Tp-e/QT in patients with acute cerebral trauma are correlated to the severity of the disease, which could be used as short-term prognostic indicators under certain conditions.
