Indications for Use
1. Persyst 13 EEG Review and Analysis Software is intended for the review, monitoring and analysis of EEG recordings made by electroencephalogram (EEG) devices using scalp electrodes and to aid neurologists in the assessment of EEG. This device is intended to be used by qualified medical practitioners who will exercise professional judgment in using the information. 2. The Seizure Detection component of Persyst 13 is intended to mark previously acquired sections of adult (greater than or equal to 18 years) EEG recordings that may correspond to electrographic seizures, in order to assist qualified clinical practitioners in the assessment of EEG traces. EEG recordings should be obtained with a full scalp montage according to the standard 10/20 system. 3. The Spike Detection component of Persyst 13 is intended to mark previously acquired sections of the patient's EEG recordings that may correspond to spikes, in order to assist qualified clinical practitioners in the assessment of EEG traces. The Spike Detection component is intended to be used in patients at least one month old. Persyst 13 Spike Detection performance has not been assessed for intracranial recordings. 4. Persyst 13 includes the calculation and display of a set of quantitative measures intended to monitor and analyze the EEG waveform. These include FFT, Rhythmicity, Peak Envelope, Artifact Intensity, Amplitude, Relative Symmetry and Suppression Ratio. Automatic event marking is not applicable to the quantitative measures. These quantitative EEG measures should always be interpreted in conjunction with review of the original EEG waveforms. 5. The aEEG functionality included in Persyst 13 is intended to monitor the state of the brain. The automated event marking function of Persyst 13 is not applicable to aEEG. 6. Persyst 13 provides notifications for seizure detection, quantitative EEG that can be used when processing a record during acquisition. These include an on screen display and the optional sending of an email message. Delays of up to several minutes can occur between the beginning of a seizure and when the Persyst 13 notifications will be shown to a user. Persyst 13 notifications cannot be used as a substitute for real time monitoring EEG by a trained expert. 7. Persyst AR (Artifact Reduction) is intended to reduce EMG, eye movement, and electrode artifacts in a standard 10-20 EEG recording. AR does not remove the entire artifact signal, and is not effective for other types of artifacts. AR may modify portions of waveforms representing cerebral activity. Waveforms must still be read by a qualified medical practitioner trained in recognizing artifact, and any interpretation or diagnosis must be made with reference to the original waveforms. 8. This device does not provide any diagnostic conclusion about the patient's condition to the user.
Device Story
Persyst 13 is EEG review/analysis software; processes scalp EEG recordings; aids neurologists in assessment. Features: automated seizure detection (adults); spike detection (>=1 month); quantitative EEG measures (FFT, Rhythmicity, Peak Envelope, Artifact Intensity, Amplitude, Relative Symmetry, Suppression Ratio); aEEG brain state monitoring; Artifact Reduction (AR) for EMG/eye movement/electrode noise. Used by qualified medical practitioners in clinical settings. Inputs: previously acquired or real-time EEG data. Outputs: marked EEG traces, quantitative displays, and notifications (on-screen/email). Notifications are not for real-time monitoring by experts. AR modifies waveforms; original data must be reviewed. Device provides no diagnostic conclusions; requires professional judgment.
Clinical Evidence
No clinical data provided. The document focuses on the regulatory determination of substantial equivalence for software functionality.
Technological Characteristics
Software-based EEG review and analysis system. Operates on standard EEG inputs (10/20 scalp montage). Includes signal processing algorithms for quantitative measures (FFT, rhythmicity, etc.) and artifact reduction. Provides automated event marking and notifications. Designed for use by qualified medical practitioners.
Indications for Use
Indicated for review, monitoring, and analysis of EEG recordings in patients. Seizure detection for adults (>=18 years). Spike detection for patients >=1 month old. Not for intracranial recordings.
Regulatory Classification
Identification
An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head.
