Electrocardiogram Quiz - Case 11

A 39-year-old woman, intubated, sedated and under inotropic agents for cardiogenic shock of four hours duration was transferred to our hospital from a maternity center. The patient had been previously hospitalized for four days after an uncomplicated childbirth. It was her second normal delivery of a healthy infant. On the day of planned discharge from hospital, she developed chest pain, dyspnea and acute pulmonary edema. The patient’s medical history was largely unremarkable, apart from Hashimoto’s thyroiditis.
