Objective To explore the clinical value of Persyst automatic detection of spike waves in adult patients with temporal lobe epilepsy. Methods EEG recordings were continuously concluded from the Epilepsy Unit of the First Affiliated Hospital of Soochow University during 2019.1.1 to 2019.12.31. Two EEG experts certified by the Chinese Anti-Epileptic Association marked interictal epileptic discharge in the long-time electroencephalogram that meet the criteria. Consistent results of the two experts were seen as the "golden standard". The sensitivity and false positive rates were calculated compared with the automatic test results of Persyst version 11, 13 and 14. Results 7 cases were included, each with a recording time of 24~25 hours and a total of 169 hours. Two expert readers achieved the consistency of 43.09%. Spike waves detected automatically were much more than manually. The sensitivity was as high as 62.26%, 77.0% and 67.28%. The lowest false positive rate was 0.37/min, 0.85/min and 0.46/min respectively. Automatic analysis achieved an average workload reduction of 14.59%~37.05%. Conclusions Persyst automatic spike detection has the acceptable sensitivity and false positive rate. It differs from versions and need to be further combined with expert readers.Less workload and accuracy can be balanced by setting reasonable perception parameter.
