An 82-year-old male presents with dyspnea worsening over the past three days.  He has a history of prior MI, hypertension, renal insufficiency and type 2 DM.  He is from out of town and is just in town for a wedding.  He is on a boatload of medications and doesn't know anything else about his history.  You are concerned about CHF and you perform a bedside echocardiogram.
