Key result
The Valsalva maneuver using a handmade device achieved a 14.8% success rate in reverting supraventricular tachycardia to sinus rhythm.
Why the study?
Does Valsalva maneuver using a handmade device improve reversion to sinus rhythm in patients with supraventricular tachycardia?
Does Valsalva maneuver using a handmade device improve reversion to sinus rhythm in patients with supraventricular tachycardia?
A handmade device for the Valsalva maneuver yielded a low success rate (14.8%) for reverting SVT, suggesting limited utility compared to modified Valsalva techniques.

Low success with handmade Valsalva device warrants clinical caution; leaves open efficacy pending randomized validation.
INTRODUCTION: The use of vagal nerve stimulation is identified as a proper treatment option in patients with stable supraventricular tachycardia (SVT). This study aimed to assess the success of Valsalva maneuver via a handmade device in reversion of SVT. METHODS: In this quasi experimental study, using a handmade device, vagus nerve stimulation was performed for SVT patients presenting to emergency department or cardiac intervention unit and the success rate and its related factors were assessed. RESULTS: 100 patients with the mean age of 53.05 ± 13.70 years were studied (67% female). 12 (12%) cases were unable to do the maneuver. Out of the 88 (88.0%) patients who could perform the maneuver, 75 (85.2%) cases were unsuccessful. Dysrhythmia was controlled in 6 (6.8%) cases on the first attempt and in 7 (8.0%) cases on the second one (14.8% total success rate). 12 of the 13 cases (92.3%) with successful maneuver had history of SVT (p = 0.031). There was not any significant association between success rate and sex (p = 0.084), age (p = 0.744), or other medical histories (p ≥ 0.05). CONCLUSION: Based on the results of the present study, the success rate of Valsalva maneuver with the mentioned handmade device was calculated to be 14.8%. The only independent related factor of successful reversion was SVT history.

Motamedi et al. (2017) studied Supraventricular Tachycardia (SVT) (n=100). Valsalva maneuver using a handmade device was evaluated on Achieving sinus rhythm following the first or second maneuver attempt. The Valsalva maneuver using a handmade device achieved a 14.8% success rate in reverting supraventricular tachycardia to sinus rhythm.
