Adenosine test appears to be at least comparable with CSNRT in making the diagnosis of SSS and may be considered as an alternative non-invasive test for confirmation of suspected SSS. No difference in the susceptibility of AVN to adenosine between the pts with syncope in the presence of SSS and those with unexplained syncope was found, suggesting that adenosine test cannot be used to diagnose atrioventricular block as the cause of syncope.

We report a case of ST elevation in right precordial leads compatible with type 1 Brugada syndrome following administration of propafenone in a patient with Wolff-Parkinson-White syndrome who was receiving lithium at concentrations within therapeutic levels. The mechanism of the electrocardiogram changes was considered to be caused by the two drugs synergistic sodium channel blocking effects.
