Does a modified Valsalva manoeuvre improve non-pharmacological reversion in patients with paroxysmal supraventricular tachycardia?
Implementing a modified Valsalva manoeuvre as a standard departmental protocol substantially increases the rate of non-pharmacological reversion for paroxysmal supraventricular tachycardia.
Our findings support previous observations that there is lack of standardisation as to how Valsalva is performed, and an apparent reliance on adenosine. The impact of introducing this technique as our departmental standard was a raise in non-pharmacological reversion from 5.3% to 31.7% with no reported significant adverse effects.
