[Peculiarities of the transitional process of heart rhythm in the active orthostasis test in healthy probands, elderly and of an advanced age].
To identify the age-related peculiarities of the transient state of the cardiac rhythm during the orthostatic test, 155 apparently healthy persons aged from 20 to 89 years were examined. The method of rhythmography was used to assess the amplitude and time characteristics of the transient processes. It was found that in aging the form of transient process undergoes a change, the amplitude of cardiac rhythm transient state is decreased, and its time characteristics duration is increased. The revealed age-associated changes seem to evidence for a worsening of the quality of cardiac rhythm regulation during the transient state in the orthostatic test.
