Abstract:
Objective To investigate the clinical features, the video electroencephalography ( V-EEG) and synchronous electrocardiography ( ECG) changes in non-epileptic seizures and the significance of ECG monitoring in the diagnosis of epilepsy.Methods We collected 3 patients who came in a chief complaint of“episodes of unconsciousness with limbs twitch”, whose clinical features and EEG, ECG in longterm VEEG monitoring were analyzed.The 3 patients were followed up for at least 6 months.Results The 3 patients were all diagnosed as epilepsy in other hospital,and during the 24-hour VEEG monitoring in our hospital,2 patients showed abnormal cardiac rate and arrest during the attack and corresponding EEG changes after cerebral ischemia and hypoxia.After consultation with the department of cardiology, they were diagnosed as cardiac syncope episode and no attack showed up after the placement of pacemaker.The Q-T interval was prolonged in the other patient during the longterm ECG monitoring, after the coherence check who was diagonsed as severe hypocalcemia combined with myocardial damage due to a lower parathyroid function and had no attack after symptomatic treatment.Conclusions The synchronous ECG monitoring during the attack is of great significance in the differential diagnosis of epileptic and non-epileptic seizures. The ECG changes in patients with longterm VEEG monitoring should be focused on.It is necessary to add the early warning function to prevent the occurrence of accidents.
