Effect of Academic Stress and Its Relationship With HRV in Young 1^St year MBBS Students

stress affects all the organs of the body, its effect on autonomic nervous system reflects end response of various organs. Academic stress is predominantly psychological and stress leads to several physiological responses such as increased heart rate variability through alteration in the autonomic activity that is increased sympathetic or decreased parasympathetic activity Management of stress with the aim to prevent its complication such as cardiovascular and cerebrovascular diseases, to improve the performance of student by relaxation technique forms the basis of this research. Consented 40 subjects were enrolled for the study, subjected to short term heart rate variability(HRV) recording for 5 minutes following standard protocol. The recording of the HRV was done using AD instruments eight channel polygraph where standard limb lead II recording of electrocardiogram (ECG) was done. To determine results of the heart rate variability lab chart 8 pro of AD instruments was used which selectively uses around 300 beats good interval artifact free for obtaining report of time domain and frequency domains of heart rate variability. This short-term recording of heart rate variability was carried on twice once the students were enrolled to the course before completion of one month and second time was before the starting of the second internal examination. Our study results highlighted the event of examination is highly challenging which is demonstrated by altered heart rate variability parameters. We suggest active intervention by means of continuous evaluation process to be replaced by one-time evaluation which currently is practiced.
