RCA-Circ involvement, also hits the innervation of the nervous system with nausea and vomiting more than your anterior MI's_ left ventricle.
I never could understand how sick an inferior wall MI could be and come out smelling like a rose with a good ef%, while a huge anterior wall would have only weakness and have a huge EF hit, only not to accept their MI as serious
Why do you have to blow out the heart to a 30 or 25% EF untill you see.. it's time for a change.... anyone else see this?
The inferiors also have tachy- brady as the sino-atrial node can be hit and afib and flutter are as common 48 hours out as a cabg!
We've two massive anterior walls with lateral and inferior extentions on my unit now, one on dobutamine, one a "functional cripple due to lack of reserve, neither ever felt "sick" or "dying" through their stay... while a massive Inferrior had rapid afib, converted with amio, a touch of diuresis with right sided failure and moved out 4 days ago, while my two anteriors are still sitting being closely guarded. doesn't make sense somedays.... the minor anterior walls to me are the hardest to gain compliance for as they just sail through as ticking time bombs... and seem more apt to be non-compliant as their course was simple and early on fixed.... yep, we see 'em later..... keeping up the teaching.
hope this helps, your inferiors are tacky-brady with frequent afib and nausea, your anteriors-lad, main, opm sail free initially. It's not uncommon for your emergent inferiors to present post cath to the ICU with transvenous pacers until 72 hours out until the sinoatrial node either steps back up, or a permanent pacer is put in. and 48 hours out, these guys are on step down when they do their rapid a fib bit... be prepared.
