The capabilities of the RHEOTEST rheograph allow the physician to obtain maximum diagnostically significant information: during the registration of the rheogram, automatic detection and classification of rheographic complexes is performed, along with generation of the differential rheogram and determination of the current heart rate value.
The ease of visual assessment of rheographic wave parameters is achieved by displaying the curve on a millimeter grid.
For convenience in conducting examinations, a protocol function is provided, which can include any number of functional tests.
Even during signal registration, primary analysis of one of the recorded complexes can be performed by selecting any complex for comparison with another—for example, one included in a different functional test, or a similar test from an examination conducted a month earlier.
The rhythmogram window allows instant identification of positions on the rheographic recording that require special attention. By clicking on a section of the rhythmogram, precise positioning on the rheographic curve is performed at the moment corresponding to a specific heart rate. On the rhythmogram, the following are color-marked: current state; segments unsuitable for analysis and marked as artifacts.
While viewing the rheogram, the display of leads can be customized according to the user’s preferences, for example, changing their order or disabling them.
During rheogram analysis, you can select a set of characteristics depending on the vascular pool being studied.
The rheograph software automatically detects and classifies rheocomplexes using markers (adjustable manually) and calculates amplitude-time parameters.
The “Magnifier” window allows analysis of the selected rheographic complex. Simultaneously with rheogram registration, rheographic complexes are automatically highlighted, the differential rheogram is displayed, and the current heart rate is determined.
Any of the recorded complexes can be analyzed and selected into a fragment group for comparison with any other part of the recording. The set of characteristics is chosen depending on the vascular pool under study. The “Complex” window displays the rheocomplex across all channels and a summary table of amplitude-time parameters. You can choose how to display the rheogram: separately by each channel, in pairs from the same vascular pool, or from the same side.
The program evaluates the nature and dynamics of rheogram changes both during a standard study and while recording functional tests.
For the analysis of the entire recorded rheogram, the ribbon can be scrolled either automatically or manually. An interesting fragment can be located and viewed using the rhythmogram. During rheogram viewing, it is possible to change the order of lead display, swap them, or disable any of them.
Heart rate variability analysis is provided: time-domain (statistical), wave structure analysis of heart rate, scattergram, and variational pulsometry according to Baevsky. Automatic description of the rheogram is generated according to the selected method and corresponding age norms. At the same time, the system allows the user to create their own system of norms and decision-making rules for any methodology.
The physician decides on the content and format of the printed report. This may include a rheocomplex with amplitude-time characteristics and an automatic description generated according to the selected method and considering age norms.
The rheograph RHEOTEST is a computerised diagnostic system for the non-invasive assessment of central and peripheral haemodynamics. It records changes in the electrical impedance of tissues associated with pulsatile blood filling of the vessels. The device is used in functional diagnostics, neurology and scientific research to assess blood circulation in the brain, limbs, internal organs and chest.
The rheograph RHEOTEST is designed for the non-invasive assessment of vascular blood filling and the functional condition of central and peripheral haemodynamics. During the examination, the device records natural changes in the electrical properties of tissues that occur with each heartbeat as the blood vessels fill with blood. Based on these data, the system assesses blood flow characteristics without invasive procedures or radiation exposure.
The device is used to assess blood flow in different anatomical areas:
In neurological practice, the equipment RHEOTEST is used to analyse cerebral circulation and assess vascular tone, arterial wall elasticity, venous outflow and other haemodynamic parameters required for the comprehensive diagnosis of vascular disorders. The simultaneous recording of several channels and automated data processing provide accurate results and increase the diagnostic value of the functional examination.
The rheograph RHEOTEST is available in three versions with different functional capabilities:
The basic configuration of the device RHEOTEST REG is intended for rheoencephalography (REG), an examination of cerebral blood circulation. It is suitable for neurology, internal medicine and functional diagnostic rooms where the primary focus is the assessment of cerebral blood vessels.
The configurations RHEOTEST REG/RVG and RHEOTEST MAX extend the system’s diagnostic capabilities and support the following functions:
The advanced functionality makes it possible to assess blood circulation in the upper and lower limbs, heart, lungs, liver and kidneys. This makes the system a versatile solution for various healthcare facilities and specialised functional diagnostic centres.
The software RHEOTEST enables real-time signal recording, digital processing and analysis of the results. The physician has access to rhythmograms, quantitative parameters, recording review tools and automated examination protocol generation.
The software automatically recognises and classifies the recorded complexes, reducing analysis time and facilitating the detection of abnormalities. The Magnifier tool is provided for the detailed review of individual recording sections. It allows signal fragments to be enlarged without losing detail and enables their visual assessment.
The rheograph RHEOTEST supports heart rate variability analysis. The software calculates the main time-domain and spectral HRV parameters used to assess the functional condition of the autonomic nervous system.
After the examination has been completed, the equipment automatically generates a protocol containing graphic materials and calculated parameters. The physician can edit the clinical conclusion, configure the report content, select the data to be printed and save the results in the electronic patient database.
