Why the study?
Ventricular fibrillation secondary to adenosine administration for PSVT is rarely reported with an incidence < 1%, highlighting the need to raise awareness of this life-threatening pro-arrhythmic effect.
Adenosine administration for PSVT can rarely induce life-threatening ventricular fibrillation even in patients without structural heart disease or pre-excitation.
No takes yet. Share an insight, caveat, or question.
Rare adenosine-associated VF in PSVT warrants clinical vigilance; leaves open determination of true incidence and risk factors.
Lee et al. (2021) studied this question.
