He was successfully defibrillated after one shock (biphasic at 200 joules). He has a history of hypertension, myocardial infarction, mitral valve regurgitation, atrial fibrillation, and hyperlipidemia. Mr. K was scheduled for mitral valve replacement and the maze procedure. Mr. K is a school administrator, is married, and has two daughters who live out of state. Clinical Assessment Mr. K is awake; follows commands; and is oriented to person, place, and time; however, he complains of weakness and severe shortness of breath despite sitting upright in bed. Procedures Mr. K’s vital signs include blood pressure of 142/82 mm Hg, pulse of 168 beats/min that is irregular and bounding, respiratory rate of 28 breaths/min, temperature of 98.2°F, and SpO2 of 92% on O2 at 2 L per nasal cannula. Further assessment reveals bilateral breath sounds with coarse crackles in the bases, S3, and a loud pansystolic murmur. Cardiac rhythm is atrial fibrillation. Chest radiograph shows cardiomegaly and bilateral congestion. Echocardiogram indicates left ventricular hypertrophy with an EF of 25%. He has negative serum cardiac enzymes; serum B-type natriuretic peptide (BNP), 1100 pg/mL; serum potassium, 3.8 mEq/dL; cholesterol, 250 mg/dL; triglycerides, 200 mg/dL; and high-density lipoprotein, 30 mg/dL.
