“…In addition, our results are in line with Dagar et al (Dagar et al, 2020) who evaluated the ECG parameters of the studied children and found that QT-min of the studied patients was 0.31 seconds. QT-max of the studied patients ranged was 0.35 seconds.…”

Introduction: Heart rate variability have the potential to serve as a biomarker of SUDEP risk, allowing for increased counselling of patients and their families and serving as a valuable outcome measure for research aimed at developing drugs and therapies to reduce SUDEP risk. The sympathetic and parasympathetic modulatory activities of cardiac nerves result in a Holter test lasting less than 24 hours (a few minutes). Objective: for detection of heart rate variability and cardiac arrhythmias in epileptic children. Materials and methods: This cross-sectional study was carried out on 100 children with epilepsy. All patients were subjected to: history taking, full physical examination, echocardiography, 24 hours Holter, EEG, MRI brain, Standard 12-derivation ECG (including V4 R derivation). Results: There was a significant variability in HF, LF, LF/HF, RMSSD, SDNN and PNN50 among all time measurements throughout the day (P values <0.001). Heart rate variability was significantly worse in younger patients aged less than 10 years than others and was found comparable between males and females (P values > 0.05). Heart rate variability was significant in relation to EEG localization (All P<0.001) being worse in case of left temporal localization when compared to other types.

“…Epilepsy is a chronic condition characterized by repeated seizures. It was previously believed that seizure control was sufficient to avert problems (Dagar et al, 2020). Heart rate variability measures give a simple, noninvasive method for evaluating the heart's autonomic control function.…”

“…[ 34 ] also found that interictal arrhythmia in patients with chronic epilepsy is similar to that in healthy people. Similarly, this study also found that there was no significant difference in QTd and QTcd between the epilepsy group and the healthy people, suggesting that there was no obvious autonomic nervous dysfunction in patients with epilepsy, but at the same time, it was inconsistent with some current studies [ 28 – 30 ]. On the one hand, the selected children were all children with primary epilepsy, the course of disease was short, and there was no myocardial damage and structural damage of cardiovascular autonomic cortex.…”

“…Dagar et al . [ 30 ] through the observation of interictal ECG in 103 patients with epilepsy, it was found that Pd, QTd, QTcd, Tp-Te dispersion (Tp-Ted) and Tp-Te/QTc ratio in patients with epilepsy were higher than those in healthy individuals. Neufeld et al [ 31 ] studied 40 patients with long-term epilepsy and found that the QTc of patients with epilepsy was longer than that of healthy individuals.…”

Background Both vasovagal syncope (VVS) and epilepsy present with transient loss of consciousness and are often difficult to identify. Hence this study aimed to explore the value of QT interval in the differentiation of VVS and epilepsy in children. Methods One hundred thirteen children with unexplained transient loss of consciousness were selected. 56 children with VVS (VVS group), including 37 males and 19 females, the average age is 9.88 ± 2.55 years old. 57 children with epilepsy (epilepsy group), including 36 males and 21 females, the average age is 8.96 ± 2.67 years old. At the same time, the 60 healthy individuals (control group) were examined according to age and sex. The QT interval of 12-lead electrocardiogram in a basal state of three groups was measured and statistically analyzed by SPSS 24.0 software. Results Compared with the control group, (1) QTcmax, QTcmin and QTcd were significantly longer in VVS group (P < 0.05), QTmax and QTmin were significantly shorter in VVS group (P < 0.05), and there were no significant differences in QTd between the two groups (P > 0.05). (2) The QTmax and QTmin were significantly shorter in epilepsy group (P < 0.05), and there were no significant differences in QTd, QTcmax, QTcmin, QTcd between the two groups (P > 0.05). Compared with the epilepsy group, The QTcmax, QTcmin, QTcd were significantly longer in VVS group (P < 0.05), and there were no significant differences in QTd, QTmax, QTmin between the two groups (P > 0.05). When QTcmax > 479.84 ms, QTcmin > 398.90 ms and QTcd > 53.56 ms, the sensitivity and specificity of diagnosing VVS were 62.5% and 77.19%, 82.14% and 50.88%, 82.14% and 38.60% respectively. Conclusion QTcmax, QTcmin and QTcd have certain value in differentiating VVS from epilepsy in children.

“…We would like to emphasize that both standard 12-lead ECG recording and interictal EEG-ECG recording have limitations and cannot replace each other. On the other side, as evaluation of ECG becomes complex regarding cardiac conduction abnormalities and sudden unexpected death in epileptic patients, 5 6 16 17 it requires complex evaluation through machines. Until machines would make it, neurologists need to assess ECG recording visually and may seek reviews on this subject.…”

We aimed to evaluate the contribution of simultaneous electrocardiography (ECG) recording during routine interictal electroencephalography (EEG) recording in patients with seizures or epilepsy and therefore to provide evidence-based data on this subject. Patients with interictal cardiac arrhythmia on routine EEG-ECG recordings were determined and evaluated based on cardiologic and neurologic findings. Out of 1,078 patients aged between 5 and 16 years (mean: 10.2 ± 3.2), 9 (0.08%) patients were found to have an arrhythmia. Six patients had both epilepsy and cardiac arrhythmia (premature ventricular contractions [PVCs] in 5; Wolff-Parkinson-White [WPW] in 1 patient) and the remaining three patients had nonepileptic paroxysmal events (NPEs) and arrhythmia (PVC in 2; WPW in 1). Three patients had other diseases (neurofibromatosis type 1, tuberous sclerosis, and congenital heart disease status postsurgery). Cardiac arrhythmia required radiofrequency ablation or antiarrhythmic drug treatment in two patients with epilepsy and also two patients with NPE; however, it improved with no specific treatment in the remaining five patients. NPE was not related to arrhythmia in one of three patients with NPE. Our study suggests that routine interictal EEG-ECG recording provides a valuable and feasible opportunity to reveal unnoticed or new-onset cardiac arrhythmias. Therefore, ECG should be recorded simultaneously during routine interictal EEG recordings. Cardiac arrhythmias detected by routine interictal EEG-ECG recordings would require arrhythmia treatment in nearly half of the patients.
