The physical examination may reveal pulmonary rales, an S3 heartsound, or extremity edema. However, physical examination findings are often not sensitive or specific.ED assessments may include electrocardiogram, complete blood count, basic metabolic profile, liverfunction tests, troponin, brain natriuretic peptide, and a chest radiograph.
