There are ancient texts and modern studies alluding to the therapeutic benefits obtained from listening to music. Studies have shown that chanting "OM" has a relaxing effect by causing parasympathetic dominance, limbic deactivation, and decreasing the brain's dopamine levels. This research aims to study the effect of listening to OM chanting on the cardiovascular system and heart rate variability and its possible use as a stress buster among medical students.
Fifty medical undergraduates were selected for the study. After a 20-minute relaxation, a lead 2 electrocardiogram (EKG) was recorded for 10 minutes. Their blood pressure (BP) and heart rate were measured. The subjects were then made to listen to OM chanting for 20 minutes, immediately after which their BP and heart rate were measured. This was followed by another 10-minute lead 2 EKG. The EKGs recorded were then used to calculate the standard deviation in N-N interval (SDNN), total power, high-frequency power, and low-frequency power.
The study reported a significant decrease in blood pressure and heart rate and a significant increase in SDNN and total power. There was also an insignificant increase in low frequency and an insignificant decrease in high frequency.
This study provides insight into the importance of spiritual music therapy in the maintenance of mental as well as cardiovascular health among medical students.
古代文献和现代研究都提及聆听音乐所带来的治疗益处。研究表明，唱诵“唵”通过引起副交感神经主导、边缘系统失活以及降低大脑多巴胺水平而具有放松效果。本研究旨在探讨聆听唱诵“唵”对心血管系统和心率变异性的影响，以及其在医学生中作为一种减压方式的潜在用途。
选取50名医科本科生参与本研究。在20分钟的放松之后，记录10分钟的II导联心电图（EKG）。测量他们的血压（BP）和心率。然后让受试者聆听唱诵“唵”20分钟，之后立即测量他们的血压和心率。随后再进行10分钟的II导联心电图记录。所记录的心电图用于计算N-N间期标准差（SDNN）、总功率、高频功率和低频功率。
该研究报告称血压和心率显著下降，SDNN和总功率显著增加。低频也有不显著的增加，高频有不显著的下降。
本研究深入探讨了精神音乐疗法在医学生心理及心血管健康维护中的重要性。
