Why did dozens of clinics go for RHEOTEST? 

1 User-friendly operation Each button is in its proper place

When working at RHEOTEST we took into account doctors’ demands and paid close attention to the device being user-friendly. For that reason, RHEOTEST is designed with the minimum set of operation elements and maximum simplicity in handling. The interface is easy to understand from mode slection to building the assessment report.

2 Individual Set Customised Approach to Every Clinic

RHEOTEST set contents depends on client needs. Where would you like to pace your device – on the wall or on a rack? Would you like to use a PC or a laptop? Which appliances do you prefer when registering a reogram? What cable length would you like to order? Our consultant will help you place your order right.

3 Easy to Relocate and Connect Mobile and Light

If you order your device on a mobile rack, you receive a mobile rheography device to serve your professional needs in different locations.

The device makes it possible to conduct a variety of research: rheoencephalography, rheovasography, rheogepathography, rheopulmonography and rheocardiography (by Kubichek and Tishchenko).

During rheogram registration it is possible to relocate main tools and extras in the panes. The user can customise band speed, rheogram and electrocardiogram amplification, curve background and main color and print out band fragments and individual complexes on graph paper.

RHEOTEST functionality enables the doctor to receive as much diagnostically important information as possible. During rheogram registration rheographic complexes are automatically highlighted and classified, differential rheogram is displayed and current HR value identified.  Rheographic wave parameters are easy to visualise with graph paper in the background of the output area

A protocol containing any number of functional tests is a handy fucntion envisaged for even more convenience when running an examination.

Preliminary analysis of one of the registered complexes is possible already during signal registration. A random complex may be selected to be compared with another complex, which may be part of a different functional test. Likewise, an analagous test taken from an examination of, say, a month before may be analysed.

The Rhythmogram Window makes it easy to immediately spot the areas on the band that require consideration. It takes one click to position a marker on the curve to capture certain heart rate. It is possible to color mark the current position and the sections not suitable for analysis and marked as artefacts.
During the review it is possible to customize lead view, for example, by changing the order in which the leads are displayed or disabled. When analysing a rheogram it is possible to select a set of characteristics with regard to the examined basin.
The software automatically identifies and classifies rheocomplexes by placing markers (marker placement is to be corrected manually) and calculates amplitude and time parameters.
The Magnifier Window displays the following elements: the rheowave, the differential curve, rheographic indexes and time characteristics of the rheo signal.
The Complex Window displays the rheocomplex channelswise and the summary table of amplitude and time parameters. You may set the way the rheogram is displayed: each channel separately, pairwise from one basin or one-sided.
The programme assesses rheogram character and time history both during a regular examination and during functional tests registration.
Heart rate variability analysis is one of RHEOTEST key functions. Such analysis looks into time history, heart rhythm wave structure, scattegram and Bayevsky’s variational pulsometry.

The doctor decides as to medical assessment report contents and layout. It may be a rheocomplex with amplitude and time characteristics and autodescription, generated in accordance with the selected method and with due regard to age appropriate normal values or a rheographic curve of the selected length and a differential rheogram.

The user builds a database using patient data stored on the computer and the registered rheograms. RHEOTEST developers considered the process with particular attention.
The database comes with a full set of functions the user needs to handle patient electronic card-index and voluminous information archives.

RHEOTEST rheoencephalography device, produced by NVP DX-Systems, was placed into service in 2005 and has been used in our diagnostic centre since then. 9457 people have been examined over the period of use. The patients with cerebral palsy, vasomotor dyscrasia, traumatic head injury, pseudo-epileptic seizures, neurological infections sequelae, diencephalic syndrome, vertebrobasilar disease and other have been referred to the diagnostic centre for examination by the doctors of the polyclinic and the in-patient hospital. Blood filling in external carotid basins and vertebrobasilar basins is examined in accordance with FM, OM leads method.
We record a reference rheogram and carry out functional tests: side-to-side head rotation, lean forward, intake of breath and nitroglycerin test.
Over the time of use RHEOTEST prooved to be a safe, reliable and effective device, which enables us to create a patient structural database.
The apparatus is used by physician of superior expert category N. Prishchenko and advanced nurse L. Khlibik
