May transiently accelerate preexcited AF; leaves open whether adenosine remains safe for diagnosing broad complex tachycardias.
Does intravenous adenosine shorten antegrade refractoriness of accessory AV connections in patients with Wolff-Parkinson-White syndrome?
Intravenous adenosine transiently shortens antegrade refractoriness of accessory AV connections, which may briefly accelerate preexcited atrial arrhythmias, but its short duration supports its safety as a diagnostic agent in broad complex tachycardias.
Garratt et al. (1991) studied this question.
