A 49-year-old male with a history of HTN, HL, DM II, and morbid obesity is admitted with a large anterior wall myocardial infarction s/p overlapping stents to the LAD for a totally occluded artery. He is 24 hours post PCI recovering in the ICU when he starts to develop recurrent chest pain, worsening shortness of breath, and hypotension. Point-of-care bedside echo is completed which reveals a large pericardial effusion with signs of tamponade. Which of the following is the MOST likely mechanical complication that this patient is experiencing post-MI?

An 88-year-old female with a history of sick sinus syndrome with a tachy-brady pattern presents to the ED with fatigue, weakness, and near-syncope. While having periods of bradycardia her blood pressure drops to 68/42 mmHg. A temporary transvenous pacemaker wire is inserted. Which of the following temporary pacemaker settings would be considered a “sensing” mode?

A 50-year-old male with a history of polysubstance abuse is brought into the ED following an out-of-hospital cardiac arrest. CPR was performed on the scene with ROSC achieved after approximately 15 minutes. He was intubated in the ED and started on vasopressors for hypotension. His urine toxicology screen is positive for cocaine. He has not started waking up yet despite not being started on sedation. Targeted temperature management will begin with a goal temperature of 36-37.5 degrees. What potential complication should be anticipated should the patient require active cooling?

An 89-year-old male with a history of HTN, hypertrophic obstructive cardiomyopathy (HOCM), and critical aortic stenosis is being considered for a transcatheter aortic valve replacement (TAVR). Prior to his procedure he presents to the ED with shortness of breath, fever, lightheadedness, and overall fatigue. CXR shows evidence of a right lower lobe pneumonia. Vital signs are as follows: temp 101.8, HR 129, RR 27, BP 82/50 mmHg, and O2 sats of 84% on RA which improve to 93% on 4L NC. He is having frequent ectopy on telemetry with a few episodes of non-sustained ventricular tachycardia.  Which of the following is the BEST choice for vasopressor support given his history and current clinical situation?

A 77-year-old male with a history of HTN, CAD s/p CABG x4, HFrEF (EF 25%), and CKD is admitted to the cardiac ICU with cardiogenic shock. He is started on Dobutamine at 5 mcg/kg/min. A bedside swan-ganz catheter was placed in order to obtain hemodynamic information. Cardiac output and index are measured by which of the following techniques?
