Do you mean the BP increases after Nitro has been given, or that BP stayes elevated after administration?
Yes, nitro is known to have a side effect of causing paradoxical hypertension after administration.

Erm...
The probable reason why the BP increased is because the atropine increased the heartrate, which often increases the blood pressure.
What was the medic doing giving atropine to someone suspected of an MI, especially if the BP was fine? Was there something else you just didn't include?

So, HR of 40, but BP fine. Was the patient altered? Pulmonary edema?
What made him treat the brady as a brady instead of as an MI? Why would he increase the workload of an ischemic heart with atropine if he suspected an MI and the BP was fine?

I honestly can't answer that. He was a Paramedic and I'm an EMT-B student so i just listened to what he told us as best I could. It may have been because he didn't have 12 lead capabilities and we did.
Is giving atropine to a bradycardic patient contraindicated if you suspect MI?

I thought y'all were talking about NITRO???
Did he give the atropine so he could give the nitro?
NTG is contra-indicated for hr < 60 b/min.
Atropine is contraindicated in an MI because, as Linuss pointed out, if the heart is ischemic, letting the sympathetic nervous system take over the body, will increase the O2 demand on an already overworked heart.
As well, the systolic blood pressure being 110, perfectly fine and no reason for any medication to be administered whatsoever.
Was the diastolic bp 110? That could be a reason to give nitro, but again, not when the HR is <60

If he gave atropine first, that would be why the bp went up. IMO. I don't know why he would give atropine to someone with an MI, unless there was symptomatic bradycardia but even then, I think atropine in an mi is a great way to kill more myocardium. Unless he was planning on running a nitro drip to make sure that pressure stayed down... In any case. Sounds like you need to ask that medic what he gave and why. We can only guess wihout he right info.
