Indications for Use
Persyst 12 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. The Seizure Detection component of Persyst 12 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. The Spike Detection component of Persyst 12 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 12 Spike Detection performance has not been assessed for intracranial recordings. Persyst 12 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. The aEEG functionality included in Persyst 12 is intended to monitor the state of the brain. The automated event marking function of Persyst 12 is not applicable to aEEG. Persyst 12 provides notifications for seizure detection, quantitative EEG and aEEG 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 12 notifications will be shown to a user. Persyst 12 notifications cannot be used as a substitute for real time monitoring of the underlying EEG by a trained expert. Persyst AR (Artifact Reduction) is intended to reduce EMG, eve 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. This device does not provide any diagnostic conclusion about the patient's condition to the user.
Device Story
Persyst 12 is software for review, monitoring, and analysis of EEG recordings; inputs are EEG signals from scalp electrodes (10/20 system). Software performs automated detection of seizures and spikes; calculates quantitative measures (FFT, Rhythmicity, Peak Envelope, Artifact Intensity, Amplitude, Relative Symmetry, Suppression Ratio); provides aEEG functionality; performs artifact reduction (EMG, eye movement, electrode). Used by neurologists/qualified practitioners in clinical settings. Output is displayed on-screen or via email notification. Software assists practitioners in EEG trace assessment; does not provide diagnostic conclusions. Practitioners must interpret quantitative measures and artifact-reduced waveforms against original EEG data. Benefits include enhanced visualization and automated marking of potential events to support clinical decision-making.
Clinical Evidence
No clinical data provided. Device relies on bench testing and performance validation of detection algorithms and quantitative measures.
Technological Characteristics
Software-based EEG analysis tool; operates on standard PC hardware. Features include automated event detection (seizures, spikes), quantitative EEG processing (FFT, rhythmicity, etc.), and artifact reduction algorithms. Connectivity includes on-screen display and email notification. Not intended for intracranial recordings.
Indications for Use
Indicated for review, monitoring, and analysis of EEG recordings in patients. Seizure detection indicated for adults (>=18 years). Spike detection indicated 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.
