[Application of computer base standards to pediatrics practice].

The computer base of medical standards to aid of pediatric diagnostic has been presented. The base include of anthropometric data (height and mass of body, some of circumferences, thickness of skinfolds etc.), analytical data (lipids) and also some of hemodynamic parameters (blood pressure). The programme allows graphical presentation of data as a percentile charts and also archives data. The basic of construction of computer base and examples of application has been presented.

Impact of cardiovascular reactions using the impedance cardiography method in borderline hypertension.

This paper evaluates the hemodynamics of 30 young men, aged 17-19 years, with borderline hypertension (BHT) and 29 normotensive (NT) patients within the same age range. The study has been carried out using the impedance cardiography method at rest and under passive orthostatic test, cold test, and hyperventilation test. In the BHT patients, the following features have been observed: increased values of the cardiac index (CI), stroke volume index (SVI), mean blood pressure (MBP), and left ventricle work index (LVWI), as well as the accompanying normal values of the total peripheral resistance index (TPRI). The reactions of the cardiovascular systems during the functional tests are similar in both tested groups; however, they are most clearly distinct in the BHT patients, where the differences are statistically significant. This may support the argument that the activity of the adrenergic system in this group in intensified.

A computer aided venous occlusion plethysmography.

A computer aided set of equipment for impedance plethysmographic research has been presented. A simple linear model of blood circulation in a limb has been used. A comparative analysis of blood circulation parameters in lower extremities has been carried out manually as well as calculated automatically. Parameters such as the limb blood flow Qo, the tissue blood flow qo, maximum volume change (venous capacitance, VC), the venous outflow time constant Tv and the venous outflow index were automatically and traditionally calculated on the basis of curve lines recorded on thermal recorder. A high linear correlation has been observed between parameters calculated manually and with computer-aided techniques. The results obtained confirm the usefulness of the linear model of blood circulation in a limb for pressures occurring under the conditions of vein occlusion.

[Rheography of the upper extremity in the diagnosis of vibration-induced vascular disorders].

The possibilities of impedance rheography in the diagnosis of the vascular form of the vibration syndrome have been presented. Three groups have been covered by the investigation: controls, subjects in occupational significant exposure to local vibration and subjects with the diagnosed vascular vibration syndrome. The rheographic investigations have been carried out synchronically from the area of hand fingers and forearms as well as under a positional test (arm elevation). Analysis of the relative pulse rate accounts for differentiating workers in the test groups. The findings confirm that the methods applied in the rheographic investigations may be a practical importance in the diagnosis of the vibration syndrome.

[Use of impedance rheography in the diagnosis of the vibration syndrome].

Each new method of studies yielding objective information on functioning disorders of those organs that get disturbed earliest is valuable for early diagnosis of vibration disease. The paper is an attempt of evaluating the usefulness of impedance reography in the diagnosis of the vibration syndrome. Analysis of basic reographic indices performed after examinations of fingers implies statistically significant differences between controls and those occupationally exposed to vibration transmitted to upper limbs.
