    Abstract: Backround: The aim of this study is to investiate whether patints with acute myocardial infarctin exhibited diurnal variatin and the relatinship between the affcted coronary artery and this diurnal variatin.Material and Methods: The patints admittd to the emergency department of Yozgat Bozok Universitywith symptoms of acute coranary syndrome between January and December 2017 were retrospectielyanalyzed. In 24 hour period diurnal changes were analyzed in 6 groups (00: 01-04: 00, 04: 01-08: 00, 08: 01-12: 00, 12: 01-16: 00, 16: 01-20: 00, 20: 01-00: 00), seasonal changes were analyzed in 4 groups (Spring,Summer, Autumn, Winter), and weekly changes were analyzed in 2 groups (Weekday, Weekend).Results: When diurnal effcts coronary arteries were examined, no statitially signifiant results werefound. When the changes of diurnal effct were observed at weekdays and weekends, it was found thatall three coronary artery lesions were statitially increased at weekdays compared to the lesions seen atweekends (p<0,05).Conclusion: Although daily diurnal variability was not detected as a result of our study, it was clearlydetermined that the increase in coronary artery disease was affcted by social reasons such as stress andintensive work pace during the weekdays

    Evaluation of Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in blunt chest trauma patients
    (2020) Çaltekin, İbrahim; Hidayet, Siho
    Abstract: 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.
