Measurements during a tonic–clonic and a complex partial seizure

3.3. Differences in measurements over all patients

Both in wakefulness (U= 29, p = 0.69) and during sleep (U = 32,

p=1.00), no significant difference in HRECG and OHR over all patients

was found.

4. Discussion

In ambulatory monitoring of patients
