Неинвазивные исследования позволяют эффективно оценивать состояние сердечно-сосудистой системы, уровень стресса и общую физиологическую устойчивость организма. Вариабельность сердечного ритма, определяемая по колебаниям временных интервалов между последовательными сердечными сокращениями, позволяет исследовать активность вегетативной нервной системы. Она отражает динамическое равновесие между симпатической и парасимпатической ветвями вегетативной нервной системы, предоставляя информацию, которая является ценным биомаркером в различных областях, включая кардиологию, спортивную науку, психологию и гигиену труда.</p></sec><sec><title>Цель</title><p>Цель.

Вариабельность сердечного ритма – колебание временных интервалов между последовательными сердечными сокращениями, представляющее собой неинвазивный показатель активности вегетативной нервной системы. Она отражает динамическое равновесие между симпатической и парасимпатической ветвями вегетативной нервной системы, предоставляя информацию о состоянии сердечно-сосудистой системы, уровне стресса и общей физиологической устойчивости. Вариабельность сердечного ритма стала ценным биомаркером в различных областях, включая кардиологию, спортивную науку, психологию и гигиену труда. Высокая вариабельность сердечного ритма обычно ассоциируется с хорошим здоровьем и адаптивностью, в то время как пониженная вариабельность сердечного ритма может указывать на стресс, усталость или патологические состояния.</p></sec><sec><title>Заключение</title><p>Заключение. Достижения в области носимых технологий и анализа данных способствовали мониторингу вариабельности сердечного ритма в режиме реального времени, что открывает более широкие возможности для клинического и личного применения в области здравоохранения.

Non-invasive studies allow for effective assessment of cardiovascular health, stress levels, and overall physiological resilience. Heart rate variability, defined as fluctuations in the time intervals between successive heartbeats, allows for the study of autonomic nervous system activity. It reflects the dynamic balance between the sympathetic and parasympathetic branches of the autonomic nervous system, providing information that is a valuable biomarker in various fields, including cardiology, sports science, psychology, and occupational health.</p></sec><sec><title>Aim</title><p>Aim.

A literature review was conducted using well-known databases such as the Russian Science Citation Index and PudMed covering a 10-year period.</p></sec><sec><title>Results</title><p>Results. Heart rate variability is the variation in the time intervals between successive heartbeats and is a noninvasive indicator of autonomic nervous system activity. It reflects the dynamic balance between the sympathetic and parasympathetic branches of the autonomic nervous system, providing information about cardiovascular health, stress levels, and overall physiological resilience. Heart rate variability has become a valuable biomarker in various fields, including cardiology, sports science, psychology, and occupational health. High heart rate variability is generally associated with good health and adaptability, while low heart rate variability may indicate stress, fatigue, or pathological conditions.</p></sec><sec><title>Conclusion</title><p>Conclusion: Advances in wearable technologies and data analysis have facilitated real-time heart rate variability monitoring, opening up broader possibilities for clinical and personal healthcare applications. This article reviews the physiological basis of heart rate variability, common measurement methods, clinical significance, and current trends in heart rate variability research and application.</p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>частота сердечных сокращений</kwd><kwd>электрокардиограмма</kwd><kwd>компьютерный анализ</kwd><kwd>автономная нервная система</kwd><kwd>оценка риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart rate</kwd><kwd>electrocardiogram</kwd><kwd>computer analysis</kwd><kwd>autonomic nervous system</kwd><kwd>risk assessment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Heart rate variability: standards of measurement, physiological interpretation and clinical use.
