I agree with the above. I work on a cardiac/stepdown (not sure if everything will overlap) but we deal a lot with MI (possible or diagnosed), CHF, a-fib and/or flutter -- these are the more common reasons someone would be on our floor vs. others. We do cardioversions, get post heart cath and/or stent, and post pacemaker placements. We even get outpatients coming in who will be discharged the same day for a pacemaker generator change or a cardioversion. As far as meds go we give lovenox like it's candy but also other anticoagulants (coumadin, pradaxa). Anti-hypertensives, beta blockers, anti-dysrrhythmics, anti-lipidemics, anti-anginals (nitro, imdur, ranexa), plavix(!!).
All of that stuff is off the top of my head. Since we are also a stepdown we also get post-thoracic surgeries (wedge resections, lobectomies, VATS, etc) unless they go to our CCU.
And (again) as the previous poster said they usually are not strictly cardiac patients. We get patients from other floors who came in with pneumonia, UTI, or mental status change when they go into a-fib and need a drip. We also get a lot of the insulin drips too and COPD exacerbations.
