Atropine Test
In the initial study aimed at evaluating vagal denervation, we employed
the atropine test (0.04mg/kg up to 2mg intravenously) to ascertain
whether any residual vagal tone remained at the conclusion of
CNA3,29. However, it should be noted
that even in cases of partial CNA, there is an immediate increase in
sinus rate, which diminishes the sensitivity of the atropine test as
sinus rate rises. Additionally, after atropine infusion, assessing
further denervation attempts becomes challenging.
