Why the study?
Does the modified Valsalva manoeuvre improve success rate in adult patients with supraventricular tachycardia?
Does the modified Valsalva manoeuvre improve success rate in adult patients with supraventricular tachycardia?
The modified Valsalva manoeuvre appears more effective than the standard manoeuvre for treating SVT in adults, reducing the need for medication without increasing adverse events.
Supports modified Valsalva as initial SVT treatment; extends evidence for higher success with fewer medications.
The available evidence is highly suggestive to support the use of the modified VM compared to the standard VM in the treatment of adult patients with SVT. Meta-analysis showed a higher success rate, required less medication use, and resulted in an equal number of adverse events. However, these results cannot be regarded as definitive in the absence of higher-quality studies.
