A simultaneous electrocardiography (ECG) recording is essential together with EEG recordings because it may prevent missed opportunities for patients in diagnostic evaluation of seizure etiology. However, it may have difficulties when patient is child or when EEG interpreter is not familiar with ECG manifestations of cardiac conductions abnormalities on EEG-ECG recordings. We present three cases (5, 10 and 12 years of age) with seizures and cardiac arrhythmias (premature ventricular extrasystoles and Wolff-Parkinson-White) remained undiagnosed and therefore aim to exemplify cost and time saving benefit of routine interictal EEGs when they are recorded with ECG simultaneously. Furthermore, these cases would be helpful to underline that EEG interpreters may be necessary to give attention to retraining on abnormal ECG findings on EEG-ECG recordings to notice when necessary in daily practice.
