Features of Changes in Heart Rate Variability among Medical Students during the Education Process.
Background: We investigated the changes of Heart Rate Variability (HRV) parameters, which reflect the state of the regulatory mechanisms of cardiovascular system, among medical students during routine academic period and examination session.
Methods: The study was conducted in Jan-Feb 2024, at the IHSM in Bishkek, Kyrgyz Republic, among the healthy 70 students (mean age 19.71 ± 1.54 years) from India and Pakistan. For each student, two ECG recordings were performed: one 3 weeks before the exam and one 10-15 minutes after exam.
Results: The results of study demonstrated that after the exam, students presented significantly higher HR, AMo, SI, VLF, LF and lower SDNN, TP, HF compared before the exam (P<0.05). Distribution of students showed that on a routine academic period 53% of students belonged to sympathotonic, 14% to vagotonic and 33% to normotonic. During the examination period the number of sympathotonic increased to 74%, but the number of vagotonic and normotonic decreased to 4% and 22% respectively.
Conclusion: Each type revealed an individual reaction to exam stress: in the group of vagotonic there was a slight activation of the SNS; in sympathotonic students there was a tension of regulatory mechanisms, leading to depletion of adaptive mechanisms; in the group of normotonic there was a shift in the vegetative balance towards the sympathetic link of ANS.
期刊介绍：
Iranian Journal of Public Health has been continuously published since 1971, as the only Journal in all health domains, with wide distribution (including WHO in Geneva and Cairo) in two languages (English and Persian). From 2001 issue, the Journal is published only in English language. During the last 41 years more than 2000 scientific research papers, results of health activities, surveys and services, have been published in this Journal. To meet the increasing demand of respected researchers, as of January 2012, the Journal is published monthly. I wish this will assist to promote the level of global knowledge. The main topics that the Journal would welcome are: Bioethics, Disaster and Health, Entomology, Epidemiology, Health and Environment, Health Economics, Health Services, Immunology, Medical Genetics, Mental Health, Microbiology, Nutrition and Food Safety, Occupational Health, Oral Health. We would be very delighted to receive your Original papers, Review Articles, Short communications, Case reports and Scientific Letters to the Editor on the above mentioned research areas.
