Posted by a Family Medicine Physician:
A 51-year-old male presented with a 10-day fever, nausea, and decreased appetite but no chest pain. While the patient had normal blood pressure, he also had an increased heart rate, electrocardiographic alterations, and a high white blood cell count. A cardiologist on Figure 1, diagnosed the patient with pericarditis — inflammation of the lining around the heart. The treating physician later confirmed this diagnosis.
