Computer rheograph Rheo

Computer rheograph RHEOTEST allows to register 1,2,4 channel rheogram and 1 ECG channel.
 

The system supplies registration of rheoencephalography, peripheral rheography, rheopulmonography, hepatorheography, rheocardiography (by Kubichek and Tishchenko).
 

Convenient and fast interface allows to add the necessary functional tests during investigation.
 

For more convenient doctor’s work during patient’s rheographic investigation it is provided the possibility of varied information about him/her, e.g. his/her work phone number.
 

System RHEOTEST is oriented for different doctor’s demands of visual rheogram presentation: setup system allows to choose tape rate, rheogram and ECG amplification, background and color of rheographic curve.
 

High quality of rheogram is provided with original schematic technical decisions of amplification.
 

There is digital filtering of high fidelity in the system, but you need not use it because of the quality of registered rheogram. The meaning of time constanta is chosen depending on investigated basin and can always be changed during registration and by rheogram review as well.

Simultaneously with rheogram registration the measurement of composite impedance and its indication has place to be. By infeasible values of base impedance the system gives warning for adjusting electrodes.    Simultaneously with rheogram registration rheographical complexes are pointed automatically out and current HRF value is determined and shown on the monitor.

 

Any registered part of rheogram can be separated to the group of fragments for being compared with any other recorded parts.
During registration in the system it is provided the possibility of low-key review any of registered complexes in “Lens” regime.
During registration regime fast print can be used and you can get paper copy of registered tape.

Rheogram processing and review

During the regime of rheograms’ analysis the following opportunities can be used:

• Recorded tape review.
• Automatic pointing of rheocomplexes, tags and calculation of amplitude temporal rheocomplex parameters with possibility of manual correction of these tags – Dialog box “Lens”.li>
• Output of all rheocomplex channels. Table’s construction of amplitude temporal rheocomplex parameters. Automatic description of rheocomplex by method given – Dialog box “Complex”.
• Automatic classification of rheocomplexes.
   
  
  Review of recorded tape
  

  For analysis of all registered rheogram it is provided the possibility of tape pan automatically or manually. To find and see an interested fragment rhythmogram will help – by one click you see chosen heart contraction.

  
   For artifacts deleting there is a wide set of plain and complicated tools in system. Field of rheogram which can not be considered, is pointed by change of background and signal’s color on the tape.

  During rheogram’s review it is possible to change sequence of lead output, change their place and cut any of them off.
  
  Dialog box “Lens”

  For rheogram’s parameters analysis it is used Lens regime in one of the channels. Rheowave, differential curve, rheographical indices and temporal characteristics of rheowave is depicted in the dialog box. At the same time applied on the output field plotting paper allows easily visual appreciate wave’s parameters.
   

  The system calculates automatically amplitude temporal characteristics of chosen wave. If necessary pointed by the program tags can be corrected by manual way.
   

  Without leaving this dialog box you can look through and review any of the former and next complexes.

  Set of characteristics is chosen according to investigated basin.
  Dialog box “Complex”

  In this dialog box chosen rheocomplex, differential rheogram by all leads and table of values of its parameters are depicted. Tags are pointed automatically in order to correct them manually. Automatical description is based on chosen method taking into account age norms.
   

  Without leaving this dialog box you can look through and review any of the former and next complexes. Out of this dialog box you may print only this complex, its parameters and automatic description. Rheograms can be depicted separately by channels and in pairs out of one basin or one side as well.
