The Role of Adrenaline in Third Degree Heart Blocks

Atropine will increase the sinus rate but it's going to have very little impact on the ventricular escape rate that we're seeing with a broad QRS complex. In this context Glenn says that he would probably choose in hospital and isoprenaline infusion or small doses of post-rosk style adrenaline. Luke Barker was asking about fluid use in bradycardia and I guess that makes a lot of sense. What he's thinking here I assume is that rather than increasing the heart rate to improve the cardiac output we could increase the stroke volume instead. That seems like a pretty sensible suggestion so I did some reading around on this but I couldn't find anything to support this practice
