Description

<p>Sudden unexpected death in epilepsy (SUDEP) typically occurs following postictal respiratory depression and cardiac abnormalities. Additionally, abnormal interictal heart rate variability (HRV), which reflects autonomic dysregulation, may have potential as a biomarker of SUDEP risk. Daily monitoring of heart rate and respiratory condition would contribute to SUDEP risk assessment and effective preventative strategies in patients with intractable epilepsy. Therefore, we have been examining the usefulness of wearable heart rate monitoring systems with garment-type electrocardiogram (ECG) sensors and their potential for clinical application in SUDEP risk assessment. Combining garment-type sensor with multiple-lead electrodes and anti-noise transmitter would optimize the accuracy in accordance with individual differences in body structure and movement. The ring-figured pulse oximeter confers a reduced feeling of restriction than that conferred by conventional oximeters; thus, the former may be a useful option for detecting respiratory disturbances.</p>
