Abstract
Background: Management of Reflex Vasovagal syncope (VVS) is challenging as no therapy has been found to be uniformly effective. Recently yoga has been proposed as a possible approach to reduce VVS susceptibility.
Objecting: The objective of this study was to evaluate the yoga maneuver - Tadasana - as an adjunctive therapy for prevention of VVS recurrences.
Methods: The study comprised 113 patients (79 men, mean age 53{plus minus}20 years) with tilt-positive VVS and structurally normal hearts . There were 61 patients in Tadasana group and 52 in the conventional arm. The Tadasana group were taught to practice this maneuver in addition to conventional therapy.
Results: Demographics of both groups were comparable. Follow up was 2 1± 5 months. At last follow - up, syncope and near-syncope events in conventional arm vs Tadasana arm were respectively 4 vs 0 (P=0.03) and 11 vs 5.(P=0.03), and the mean total events during this period in the 2 groups were 6.20 ± 9.43 vs 3.13 ± 2.08 , (P= 0.024). Syncope and near-syncope events were respectively 1.77 ± 1.29 vs 1.25 ± 1.28 (P= 0.035) and 0.38 ± 1.05 vs 0.10 ± 0.35,( P=0.048). Compared to pre-treatment, the reduction in total events in Tadasana group was significantly greater than in the conventional arm (6.10 {plus minus} 9.43 vs 3.13 ± 2.0, P=0.01). Tadasana intervention was associated with greater reduction in both syncopal and near-syncope end-points individually.
Conclusion: Adjunctive practice of Yoga maneuver-Tadasana with conventional therapy appears to reduce susceptibility to reflex VVS.
