Frequency of peri-ictal apnea and cardiac arrhythmias in epileptic seizures

Abstract Background Available data from witnessed and monitored sudden unexpected death in epilepsy (SUDEP) cases postulate that ictal central apnea (ICA) arrhythmias are the main causes of SUDEP. ICA is a frequent semiological feature focal occasionally only clinical manifestation seizures. The aim this study was to assess frequency cardiac epileptic patients risk factors predictors their occurrence. Methods Fifty diagnosed with were recruited study. All participants underwent prolonged surface video electroencephalography (VEEG) using 10-20 international electrode system concomitant polysomnography including electrocardiography (ECG), heart rate monitoring, peripheral capillary oxygen saturation (SpO 2 ) pulse oximetry. Also inductance plethysmography used record chest abdominal excursions. Results Complete datasets available 50 112 seizures recorded. occurred exclusively ( P <0.001). Temporal lobe associated higher occurrence comparison extratemporal In addition, lateralized left hemisphere On other side, tachycardia found be more temporal hemispheric seizure onset Conclusion magnitude seizures, both had percentage types onset.
