True or false? Atropine doses of less than 0.5mg may paradoxically result in further slowing of the heart rate.
true- atropine crosses into the CNS stimulating the vagus nerve causing bradycardia at low doses. At higher doses the muscarinic blocking effects of Atropine out weigh the CNS effects, causing tachycardia.
