I think Glucagon and calcium chloride are the first line agents.

Dopamine and Dobutamine are both Beta agonist but I think Dopamine is a better drug in block as it also increases renal perfusion and is better in Heart Failure condition.

So most Probably its Dobutamine.

hahaha..this qs is a really old qs...the "correct" answer is Dobutamine...but I think is not right

All the following drugs are recommended for treatment of beta blocker induced excessive bradycardia and/or decrease in cardiac output, except ?
A) Dopamine = low-medium doses (high dose will increase afterload via alpha1)
B) Dobutamine = will increase CO (mostly use in Systolic dysfunction via beta1)
C) Glucagon = treatment of b.b intoxication
D) Calcium chloride = will increase CO, but will produce bradycardia (reflex)

here is the source of the qs
http://www.aippg.net/forum/f15/treat...induced-80971/

So, Dobutamine will increase CO, and also could increase HR (discrete effect though)....
