title: [Systolic time interval as a means of evaluating the cardiac functional capacity in patients with and without heart insufficiency].
abstract: Determining the systolic time intervals in a non-invasive method which is easy to apply and inexpensive, and it can be repeated as many times as necessary. The patient is subjected to low psychic stress so that even elderly and sick patients may undergo it. The STI method may be applied to case control and the observation of the development of a disease following pharmacological treatment. The method makes it possible to differentiate between healthy persons and patients suffering from cardiac insufficiency, and concealed insufficiencies of the cardiac circulation may be detected. The STI interpretation must take into account those factors which have an effect on the STI length. The results can be considerably upgraded through the use of certain indices, PI being the main one. The PI index is of particular value if the effect of the treatment by glycoside medication is to be observed.
