Open Access e-Journal Cardiometry No.16 May 2020
We should mention that Cardiometry is a fine diagnostics tool to assess heart life expectancy. Our experts, using Cardiocode in “red zones” in intensive care units, have confirmed effectiveness of noninvasive measuring of the hemodynamics data on the cardiovascular system performance in critical patients with different severity degrees. The medical staff involved had a possibility not only to monitor the state in each critical patient, but also to predict and control the progression of a disease. We are going to publish some results of this pilot study in our next issues. We should mention that Cardiometry is a fine diagnostics tool to assess heart life expectancy.

As a rule,when preparing to examinations, the highest attentionis focused on the cognitive component of an individual'sreadiness, which relates to either a demonstrationof a specific knowledge or skills of applying theknowledge in practice. But at the same time, a psychophysiologicalstate of an individual, which is the mostimportant component of his/her readiness to the examinationsof any type, often falls beyond the scope ofthe focused training and is out of sight for researchersof such trainings. In this respect, even the unified stateexamination (USE), which is an object for stormy publicand political debates, is not an exception. It seemsto be at least strange against the background of tensof thousands of investigations in the field of pedagogyand sociology, which try to prove the effectiveness ofthe above form of knowledge assessment, consideringits importance for education system and students’training. Besides, in the early years of the USE introduction,sometimes appeared some works of psychologistswith their recommendations on how studentsshould improve the effectiveness of their preparationfor examinations, but now such recommendationshave been replaced by polemical notes of supportersof either negative or positive attitude towards theseexaminations.It is also surprising that the issues of influence ofthe personological characteristics of the student as asubject in the educational activity on his/her effectivenessof coping with stress of such kind remain still insufficientlystudied. But without studying the aboveissues, all programs of psychophysiological trainingto examinations become impersonal. In this case, theprograms tend to formulate a set of some general-purposeguidelines, which are based, at best, on just acommon sense and life experience. Their justificationand possible adjustment still require a more in-depthstudy of relation of psychophysiological readiness andpersonal characteristics of the students with their successin overcoming examinations.To a large extent, the reason for this lack of attentionto the psychophysiological component of the students’readiness to examinations is the absence of reliablemeans to measure this decisive component.

12], we may assume that PC-assisted cardiographs ofthe Cardiocode type and modern portable eyetrackerscan serve as the above mentioned measuring instrumentation.Our hypothesis takes into considerationthe fact that, as shown in [1-4, 6, 8, 12], Cardiocodemakes it possible to identify the nature of the respondents’affective response to certain stimuli using heartrate variability and Baevsky stress index (SI). Eyetrackerscan also be successfully employed in evaluating thepersonal characteristics of respondents [13]. In addition,we demonstrate in [2, 11, 12] that the level andthe nature of the respondent’s stress reactions to visualstimuli can also be estimated based on oculographicdata using the autonomic coefficient by Shiposh (AC)and the total deviation from the autogenic norm (TD)calculated on the basis of the Lüscher color test [15].Materials and methodsTo test the above hypothesis in the first part of ourstudy, a complete set of subtest visual stimuli preparedas on paper sheets of the A-4 format, contained imagesas listed below, has been given to respondents:toothy jaws of an attacking vampire bat;a pretty image of a giant panda;a huge spider devouring a wasp;a rattlesnake preparing to attack;a funny kitten playing around;150-point typed word EXAMINATION;190-point typed word SESSION;a standard form of answers, which is used duringthe USE procedure.During an alternate demonstration of each stimulusto respondent for 15 seconds an ECG has been recordedwith the CARDIOCODE device, which allowsan automatic calculation of Baevsky stress index (SI)values.In the second part of the experiment, the abovevisual stimuli have been presented individually toeach respondent on the screen of the GP-3 portableeyetracker. The complete set of the stimuli includedthe following images in this case:110-point typed words GOOD MOOD surroundedby eight color squares from the Lüscher test;150-point typed words EXAMINATIONS surroundedby eight color squares from the Lüscher test;190-point typed word SESSION surrounded byeight color squares from the Lüscher test;located in the same places, eight color squares fromthe Lüscher test without any other images or wording;Figure 1.

Abstract
Cardio-oсulometric indicators to grade psychophysiological
readiness of students to examinations are described herein.
Given is an experimental evidence that transitions from a low
level of psychophysiological readiness of students to examinations
to a high level of such readiness thereto is really accompanied
by significant changes in the organism performance, first
of all, in that of the heart. It is shown that a reliable marker of
such changes is the heart rate variability assessment using the
Baevsky stress index (SI), as well as the oculometric peculiarities
of response to the visual stimuli, which students associate with
their upcoming examinations.

Introduction
Academic examinations are one of the repetitive
stress stages in life of a modern individual. As a rule,
when preparing to examinations, the highest attention
is focused on the cognitive component of an individual's
readiness, which relates to either a demonstration
of a specific knowledge or skills of applying the
knowledge in practice. But at the same time, a psychophysiological
state of an individual, which is the most
important component of his/her readiness to the examinations
of any type, often falls beyond the scope of
the focused training and is out of sight for researchers
of such trainings. In this respect, even the unified state
examination (USE), which is an object for stormy public
and political debates, is not an exception. It seems
to be at least strange against the background of tens
of thousands of investigations in the field of pedagogy
and sociology, which try to prove the effectiveness of
the above form of knowledge assessment, considering
its importance for education system and students’
training. Besides, in the early years of the USE introduction,
sometimes appeared some works of psychologists
with their recommendations on how students
should improve the effectiveness of their preparation
for examinations, but now such recommendations
have been replaced by polemical notes of supporters
of either negative or positive attitude towards these
examinations.
It is also surprising that the issues of influence of
the personological characteristics of the student as a
subject in the educational activity on his/her effectiveness
of coping with stress of such kind remain still insufficiently
studied. But without studying the above
issues, all programs of psychophysiological training
to examinations become impersonal. In this case, the
programs tend to formulate a set of some general-purpose
guidelines, which are based, at best, on just a
common sense and life experience. Their justification
and possible adjustment still require a more in-depth
study of relation of psychophysiological readiness and
personal characteristics of the students with their success
in overcoming examinations.
To a large extent, the reason for this lack of attention
to the psychophysiological component of the students’
readiness to examinations is the absence of reliable
means to measure this decisive component. However,
