Evaluation of Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in blunt chest trauma patients

BACKGROUND: After blunt chest trauma, life-threatening arrhythmias may occur in the early post-injury period, as well as a few days after the injury. This study aimed to evaluate the risk of arrhythmias in blunt chest trauma patients using Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio.
METHODS: In this study, patients who applied to the emergency department due to blunt chest trauma were examined prospectively. The 12-lead ECG was performed to both blunt chest trauma and control group. ECG measurements of QT and Tp-e intervals were performed from both groups.
RESULTS: A total of 81 participants; 41 blunt chest trauma patients and 40 healthy volunteers were included in this study. Tpe, Tpe/QT, Tpe/QTc values were statistically significant in the trauma group compared to the control group (p<0.001). Although Tpe/QTc, max QT and min QT were statistically significant (p<0.05) in patients with a rib fracture, no difference was detected concerning Tpe, Tpe/QT compared to no-rib fracture group (p>0.05).
CONCLUSION: Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in ECG predict the arrhythmias that may occur in blunt cardiac trauma, especially in blunt chest trauma patients.

Künt göðüs travmasý hastalarýnda Tp-e aralýðý, Tp-e/QT oraný ve Tp-e/QTc oranýnýn deðerlendirilmesi

AMAÇ: Künt göðüs travmasýndan sonra, yaralanma sonrasý erken dönemde ve yaralanmadan birkaç gün sonra hayati tehlike oluþturan aritmiler ortaya çýkabilir. Bu çalýþmada, künt göðüs travma hastalarýnda Tp-e aralýðý, Tp-e/QT oraný ve Tp-e/QTc oraný kullanýlarak aritmi riskini deðerlendirmeyi amaçladýk.
GEREÇ VE YÖNTEM: Bu çalýþmada künt göðüs travmasý nedeniyle acil servise baþvuran hastalar ileriye yönelik olarak incelendi. Künt göðüs travmasý ve kontrol gruplarýna 12 derivasyonlu EKG uygulandý. Her iki gruptan da QT ve Tp-e aralýklarýnýn EKG ölçümleri yapýldý.
BULGULAR: Kýrk bir künt göðüs travmalý hasta ve 40 saðlýklý gönüllü olmak üzere, toplamda 81 katýlýmcý çalýþmaya dahil edildi. Tpe, Tpe/QT, Tpe/QTc deðerleri travma grubunda kontrol grubuna göre istatistiksel olarak anlamlýydý (p<0.01). Her ne kadar Tpe/QTc, maksimum QT ve min QT, kaburga kýrýðý olan hastalarda istatistiksel olarak anlamlý olsada (p<0.05) kaburga kýrýðý olmayan gruba göre Tpe, Tpe/QT açýsýndan fark bulunmadý (p>0.05).
TARTIÞMA: EKG’de Tpe aralýðý, Tp-e/QT oraný ve Tp-e/QTc oraný, künt kardiyak travmada, özellikle künt göðüs travma hastalarýnda oluþabilecek aritmileri öngörmektedir.
