I work in a mixed MICU/SICU. My facility also has a CICU and Neuro/TraumaICU, so we don't see a lot of hearts, heads or trauma.
SICU patients are post-op patients that require critical care. Here's the scenario that brought in one of my recent patients. He presented at another small facility with chest pain and had elevated trops. They xfered him to our facility to go for a heart cath. However he was complaining of abdominal pain instead of chest pain when he arrived and had stated his abdomen had been distended and painful for 2 weeks. CT showed ischemic bowel, he went to surgery and they did an appendectomy, released a midgut volvulus. He came to the ICU with his midline incision remaining open with vacuum closure, pressors to maintain BP, ventillator, PCA for continuous morphine, multiple drains. When he returned to the OR for closure of the midline incision, he also had a cholecystectomy for gangrenous gallbladder and a gastrojejunostomy tube placed. On his date of admission, he looked like he had one foot in the grave. He was extubated yesterday, slightly confused, but improving tremendously.
MICU patients are medically unstable. Lately, I've been seeing a lot of respiratory failure, pneumonia, kidney failure, sepsis, and overdoses stand out as well as a variety of other chronic conditions.
I think to best prepare...hrm...I'd brush up on your cardiac rhythms, mechanical ventilation, hemodynamics. The resources listed at

Good luck in what you decide to do!
