Key result
Yogic practices attenuate orthostatic hypotension and reduce syncope frequency in recurrent VVS.
Why the study?
Existing management therapies for OH and VVS have modest effect, while recent studies have demonstrated the efficacy of yoga and pranayama in disorders with autonomic imbalance.
Do yogic practices (yoga and pranayama) reduce the frequency of attacks of syncope and presyncope in patients with orthostatic hypotension and recurrent vasovagal syncope?
Systematic Review
Do yogic practices (yoga and pranayama) reduce the frequency of attacks of syncope and presyncope in patients with orthostatic hypotension and recurrent vasovagal syncope?
Yoga and pranayama may be beneficial in managing orthostatic hypotension and reducing the frequency of vasovagal syncope, though higher-quality trials are needed.
OH and VVS are increasingly recognized as important causes of impairment of quality of life and potentially of poor prognosis. Existing management therapies have modest effect. Recently few studies have emerged and have demonstrated the efficacy of yoga and pranayama in disorders having autonomic imbalance, suggesting its possible efficacy in OH and VVS. This review aims to determine the effectiveness of yogic practices in patients with orthostatic hypotension (OH) and recurrent vasovagal syncope (VVS). A Medline search was done in Google chrome to review relevant articles in English literature considering the eligibility criteria that the article should focus on yoga and pranayama and its physiological effects on OH and VVS. The main outcome expected was attenuation of OH and frequency of attacks of syncope and presyncope. : Out of the total 86 articles searched, 7 articles (3 RCTs, 3 observational/interventional, 1 review) full filled the eligibility criteria and depicted that yogic practices can have positive impact in attenuation of orthostatic hypotension and reduce the frequency of attacks of syncope and presyncope, among patients with recurrent VVS. However, we recommend higher-quality RCTs in future to confirm our results.

Balaji et al. (2023) conducted a systematic review in Orthostatic hypotension and vasovagal syncope. Yoga and pranayama was evaluated on Attenuation of orthostatic hypotension and frequency of attacks of syncope and presyncope. A systematic review of 7 articles found that yogic practices can attenuate orthostatic hypotension and reduce the frequency of syncope and presyncope attacks in patients with recurrent VVS.
