Key result
Modified Valsalva maneuver triggers non-sustained polymorphic VT in a pregnant patient with SVT.
Why the study?
Serious adverse events associated with the modified Valsalva maneuver for treating supraventricular tachycardia are not well documented.
Does the modified Valsalva maneuver cause adverse events in pregnant patients with supraventricular tachycardia?
Case Report (n=1)
Does the modified Valsalva maneuver cause adverse events in pregnant patients with supraventricular tachycardia?
The modified Valsalva maneuver may be associated with serious adverse events such as non-sustained polymorphic ventricular tachycardia in pregnant patients.
Potential proarrhythmia risk in pregnancy warrants caution with modified Valsalva; single case leaves open true incidence and causality.
The modified Valsalva maneuver has been promoted as a safe and effective method for the treatment of supraventricular tachycardia. Serious adverse events associated with the modified Valsalva maneuver are not well documented. Here we report a case of non-sustained polymorphic ventricular tachycardia in a pregnant patient associated with the use of the modified Valsalva maneuver by paramedics in the prehospital setting.

Lapalme et al. (2021) conducted a case report in Supraventricular tachycardia (n=1). Modified Valsalva maneuver was evaluated on Non-sustained polymorphic ventricular tachycardia. The modified Valsalva maneuver induced non-sustained polymorphic ventricular tachycardia in a pregnant patient with supraventricular tachycardia in the prehospital setting.
