Atropine can cause:
Decreased cardiac output
Heart block
Hypertension
Mydriasis
Atropine is an anticholinergic drug. It causes increased heart rate.
Atropine causes mydriasis and decreased sweating.
No consistent or marked effect on BP, though hypotension may occur due to histamine-release and direct vasodilator action (at high dose); tachycardia and vasomotor centre stimulation tend to rise BP.
