Does the Valsalva Manoeuvre improve termination of SVT in patients with supraventricular tachycardia?
Current evidence is insufficient to determine the effectiveness of the Valsalva manoeuvre for terminating supraventricular tachycardia, highlighting the need for standardized research.
We did not find sufficient evidence to support or refute the effectiveness of VM for termination of SVT. Further research is needed, and this research should include a standardised approach to performance technique and methodology.
Smith et al. (Wed,) studied this question.
