THE CLINICAL SIGNIFICANCE OF HEART RATE VARIABILITY (HRV) IN CARDIOVASCULAR RISK PREDICTION

Аннотация

Heart Rate Variability (HRV) represents the physiological variation in time intervals between successive heartbeats and serves as a non-invasive indicator of autonomic nervous system activity. Decreased HRV has been strongly associated with an increased risk of cardiovascular events, including myocardial infarction, heart failure, and arrhythmias. This article explores the physiological basis of HRV, its measurement techniques (time-domain and frequency-domain analyses), and its clinical relevance in cardiovascular risk prediction. It further discusses the potential of HRV as a tool for early diagnosis and for developing personalized therapeutic strategies in cardiology. Keywords: heart rate variability, cardiovascular disease, autonomic nervous system, diagnosis, arrhythmia, myocardial infarction YURAK URISH CHASTOTASI VARIABELLIGINING YURAK-QON TOMIR KASALLIKLARI XAVFINI BAHOLASHDAGI KLINIK AHAMIYATI Nuralieva Dilbar Toshkent tibbiyot akademiyasi Termiz filiali talabasi Annotatsiya: Yurak urish chastotasi variabelligi (HRV) yurak urishlari orasidagi intervallar o‘zgaruvchanligini ifodalaydi va avtonom asab tizimining yurak faoliyatiga bo‘lgan ta’sirini baholashda muhim ko‘rsatkich hisoblanadi. HRV ko‘rsatkichining past darajasi yurak-qon tomir kasalliklari, jumladan, yurak xurujlari, yurak yetishmovchiligi va aritmiyalar xavfining ortishi bilan chambarchas bog‘liq. Mazkur maqolada HRVning fiziologik asoslari, baholash metodlari (vaqt va chastota sohalarida tahlil), shuningdek, uning yurak-qon tomir xavfini prognozlashdagi klinik ahamiyati tahlil qilinadi. HRV asosida erta diagnostika va individual davolash strategiyalarini ishlab chiqish imkoniyatlari yoritiladi. 366 Acumen: International Journal of Multidisciplinary Research Acumen: International Journal of Multidisciplinary Research ISSN: 3060-4745 IF(Impact Factor)10.41 / 2024 Volume 2, Issue 6 Kalit so‘zlar: yurak urish chastotasi variabelligi, yurak-qon tomir kasalliklari, avtonom asab tizimi, diagnostika, aritmiya, yurak xuruji
