Does phenylephrine abolish refractory supraventricular tachycardia in a patient with Wolff-Parkinson-White syndrome?
Vasopressor therapy with phenylephrine may be considered for refractory tachyarrhythmias in Wolff-Parkinson-White syndrome when circumstances permit.
A patient with Wolff-Parkinson-White syndrome, susceptible to tachydysrhythmias , presented for eye surgery under general anaesthesia. He developed a supraventricular tachycardia refractory to a variety of treatments. Phenylephrine consistently abolished the dysrhythmia, probably by acting directly to stimulate the arterial baroreceptors and hence vagal output. Vasopressor therapy should be considered in Wolff-Parkinson-White syndrome tachyarrhythmias, when circumstances permit.

Jacobson et al. (1985) conducted a case report in Wolff-Parkinson-White syndrome (n=1). Phenylephrine vs. Other treatments (refractory) was evaluated on Abolition of dysrhythmia. Phenylephrine consistently abolished refractory supraventricular tachycardia in a patient with Wolff-Parkinson-White syndrome.
