[Time serial study of orthostatic cardiovascular regulations].
In a repeated measurement design (16 times during 8 weeks) active orthostasis was investigated in a sample of twenty male students, utilizing a tilt table. Additional data included cardiovascular and pulmonary tests, psychological scales, items from a diary and meterorological data. Analysis of orthostatic time-series was carried out with hierarchical grouping analysis for heart rate and blood pressure. Results indicated three intraindividual patterns of orthostatic reaction called normo-, hyper- and hyporeactive. These patterns are independent of the known interindividual orthostatic reaction types. Analysis of variance of the described patterns revealed differences for physiological and meteorological data and some items of the diary. These results have been crossvalidated.
