INTRODUCTION: Patients who have electrical accidents can apply to hospital with clinical signs ranging from simple skin burns to serious organ injuries. Our aim in this study is to evaluate whether QT, QTc interval and QT/QTc, Tp-e/QT, Tp-e/QTc ratios can be a marker for determine the risk of arrhythmias in children in cases of electric shock injuries that can be fatal.

MATERIAL & METHOD: In our study, 36 patients who were admitted to pediatric emergency with an electric shock between July 2018 and September 2019 and followed up in our clinic were included. As a control group, 25 healthy patients were included in the study. The files of the patients were examined retrospectively ECG (electrocardiogram) findings in leads DII and V5 were recorded.
RESULTS: Thirty-six (41%) patients who were admitted to our study due to electrical shock and followed up in our pediatric emergency were included. Sinus tachycardia was observed in two patients and no arrhythmias were detected in others. There was no statistically significant difference between the two groups between QT, QTc interval and QT/QTc, Tp-e/QT and Tp-e/QTc ratios measured in DII and V5 leads on ECG (p> 0.05). There was no statistically significant difference between ECG findings by gender(p> 0.05).

CONCLUSION: Electric shock can cause life-threatening situations by causing fatal arrhythmia. Although ECG findings are used to determine cardiac arrhythmia, it should be shown whether QT, QTc interval and Tp-e/QT, Tp-e/QTc ratios are significant arrhythmogenic markers by prospective studies in more specific age groups.

Amaç: Elektrik kazaları basit cilt yanıklarından ciddi organ yaralanmalarına kadar değişen klinik bulgu ile gelebilmektedir. Elektrik çarpmaları sonrasında hayati tehdit eden kardiyak ritim bozuklukları görülebilmektedir.Bu çalışmadaki amacımız aritmiye neden olarak ölümcül olabilecek elektrik çarpmasına bağlı yaralanmalarda QT, QTc sürelerinin ve QT/QTc, Tp-e/QT, Tp-e/QTc oranlarının çocuklarda aritmi riskini belirleyebilecek bir belirteç olup olmadığını değerlendirmektir.
Materyal method: Çalışmamızda Temmuz 2018 ve Eylül 2019 tarihleri arasında elektrik çarpması şikayeti ile başvuran ve çocuk acilimizde takip edilen 36 hasta alındı. Kontrol grubu olarak da sağlıklı 25 hasta çalışmaya alındı. Hastaların dosyaları retrospektif olarak incelenerek yaş, cinsiyet, klinik bulgu ve fizik muayene bulgusu, vital bulgular, yapılan tedavi ve sonuçları, EKG(elektrokardiyogram) bulguları, DII ve V5 derivasyonlarında QT, QTc süreleri ve QT/QTc, Tp-e/QT ve Tp-e/QTc oranları kaydedilmiştir.
Bulgular: Çalışmamıza elektrik çapması nedeni ile başvuran ve çocuk acilimizde takip edilen 36(%41) hasta alındı. Tüm hastalar çocuk acil servisinde monitorize edilerek hidrasyon ve semptomatik tedavi ile 24 saat takip edilip şifa ile taburcu edildi.İki hastada sinus taşikardisi görüldü diğerlerinde aritmi saptanmadı. EKG' de DII ve V5 derivasyonlarında ölçülen QT, QTc süreleri ve QT/QTc, Tp-e/QT ve Tp-e/QTc oranları arasında her iki grup arasında istatistiksel olarak anlamlı farklılık yoktu (p>0.05).Erkek kız gruplarına bakıldığında da cinsiyet ve EKG'deki QT, QTc süreleri ve QT/QTc, Tp-e/QT ve Tp-e/QTc oranları arasında istatistiksel olarak anlamlı bir farklılık saptanmadı(p>0.05)
Sonuç: Elektrik çarpması malign aritmiye sebep olarak hayatı tehdit eden durumlara sebep olabilir. Kardiyak aritmiyi belirlemede EKG bulguları kullanılmakla birlikte daha çok sayıda belirli yaş gruplarında prospektif yapılacak çalışmalarla QT, QTc sürelerinin ve Tp-e/QT, Tp-e/QTc oranlarının anlamlı aritmojenik bir belirteç olup olmadığı gösterilmelidir.
