After the measurement is finished, the following procedures/keys can be used:
After any of the Ewing’s tests is finished, save, please, (by clicking on the ‘Save’

button below) the recorded data immediately. Afterwards, the patient’s record and
identification information is displayed, as well as graphics displaying the heart rate
course during the whole test and all relevant statistical results – click on the

‘Results’ button below.

Relevant parameters: Deep breathing test

HRrest :

Resting heart rate

MV:

Average R-R interval

SD:

Standard deviation

MSSD:

Mean Square of Differences of Successive R-R Intervals

CVr-r :

Component Variance of R-R Intervals

I-E:

Difference Inspirium and Expirium heart rate

I/E:

Ratio maximum vers. minimum heart rate during Inspirium

and Expirium

Practical example: Typical results screen with apparently normal heart
rate variability during the deep breathing test. For parameters
description, see above. The green lines in the main screen show time
course of test commands (5-seconds cycles), ECG below, position of the

browser of heart rate course and numbers shown at the bottom line are
related to the marked HR value – in yellow, see the main screen. In
order to remove artefacts, the marking can be changed by moving the

mouse and clicking the left (mark) or right (unmark) buttons. This
procedure is identical with that used in spectral analysis processing, as
described earlier.
