AbstractSupraventricular tachycardia is a common cardiac arrhytmia with recurrent episodes. The rapid resolution of supraventricular tachycardia remains a challenge. Vagal manoeuvres are simple and non-invasive but yield positive results in less than half the cases. Currently, the modified Valsalva manoeuvre appears to be the most effective technique. We have tested the effectiveness of the reverse Valsalva manoeuvre without swallowing as new vagal manoeuvre for the treatment of supraventricular tachycardia. This new technique is easy to perform and can be carried out alone by the patient. We report in this series 11 cases of supraventricular tachycardia, 10 of which were effectively reduced after the completion of the reverse Valsava manoeuvre. The very encouraging results of this series of cases will have to be quickly evaluated by a randomised controlled trial. This new technique, which is simple to learn and carry out, could be easily taught throughout the world, including in regions with few health-care resources.Copyright © 2020 Elsevier Inc.
