“…In studies on mitral valve prolapse and ECG findings in children, the interval of QT, QTc, Tp-e and the ratios of Tp-e/QT and Tp-e/ QTc were significantly increased. [23] Turker et al [25] did not detect a significant difference in QT and QTc interval in mitral valve prolapsus patients with ventricular arrhythmia.…”

“…Türe et al [23] In their study with children who had dilated cardiomyopathy and exitus, they found a statistically significant difference in QT, QTc and Tp-e interval. In studies on mitral valve prolapse and ECG findings in children, the interval of QT, QTc, Tp-e and the ratios of Tp-e/QT and Tp-e/ QTc were significantly increased.…”

“…[16] There are studies in the literature showing that QTc, Tp-e interval and Tp-e/QT and Tp-e/QTc ratios are arrhythmogenic markers associated with cardiovascular mortality and morbidity. [23] Although studies in the literature in children are limited, there are no studies on Tp-e and Tp-e/QT interval in ECG related to electric shock in children. Karataş et al in their study of electric shock in adults, QTc, QTD, Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio were significantly longer compared to patients' admission and control ECGs.…”

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 and 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). Also there was no statistically significant difference between ECG findings of genders(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.

“…In our study, the most common electrocardiography findings was left ventricular hypertrophy and we observed that the mortality rate was statistically higher in patients with ECG findings. Türe et al [15] reported that, the significant difference was seen between the electrocardiographic findings of deceased and surviving patients with DCM and they suggest that detailed ECG wave measurements should be evaluated in children to define the risk of mortality.…”

Dilated cardiomyopathy is characterized by impaired myocardial contractility and cardiac dilatation. Most cases in children are idiopathic despite diagnostic developments. In this study, we aimed to review children with dilated cardiomyopathy and attempt to determine the prognostic factors. Materials and methods: A total of 59 children with a diagnosis of dilated cardiomyopathy were evaluated retrospectively between January 2005 to January 2013.The age of onset of symptoms, gender, parental consanguinity, electrocardiography findings, presence of cardiomegaly in the telecardiograpy, left ventricular ejection fraction and shortening fraction on prognosis were evaluated. Results:The mean age of patients was 49.2±59.2 months and the male/female ratio was 1.03/1. Heart failure symptoms and signs were the most common cause of admission.The most common electrocardiographic finding was left ventricular hypertrophy in 32.2% and cardiomegaly was observed on telecardiography in 77.8%. The left ventricular ejection and shortening fraction of patients' were 38.4±14.5% and 18.8±8.4% at the time of the diagnosis and 51±18.6% and 26.8±11.6% at the end of the follow-up, respectively.The mean follow-up period was 27.5±27.7 months and the mortality rate was 42.4%. The main factors affecting prognosis have been found as detection of electrocardiographic changes, cardiomegaly, and lower left ventricular ejection fraction at the time of the diagnosis. Conclusion:Dilated cardiomyopathy remains a challenging disease and the prognosis is poor. In our study, the most important prognostic markers affecting survival were determined by the presence of electrocardiographic changes, cardiomegaly, and a reduced ejection fraction.

“…Pd is a new maker of abnormal atrial conduction in ECG leads in different directions, reflecting inhomogeneous and slow atrial conduction. Increased Pd is a reliable predictor of atrial fibrillation and is associated with SCD and severe ventricular arrhythmia (4,8,9). P-wave terminal force in lead V1 (PTFV1) is the product of the negative terminal P-wave amplitude and the negative P-wave time in lead V1.…”

Predictive value of electrocardiographic markers in children with dilated cardiomyopathy

Dilated cardiomyopathy (DCM) refers to a heterogeneous group of cardiomyopathies characterized by ventricular dilatation and myocardial systolic dysfunction, which can lead to serious consequences such as malign arrhythmia, sudden death, heart failure, and thromboembolism. With its economical, non-invasive, simple and reproducible advantages, electrocardiogram (ECG) has become an important indicator for assessing the prognosis of cardiovascular diseases. In recent years, more and more studies of electrocardiography on DCM have been carried out, but there is still a lack of a comprehensive summary of its prognostic value. This article reviews the prognostic value of electrocardiographic markers in children with DCM.
