Summary

Patients with pulmonary embolism (PE) can show changes on the ECG. Here, we report the case of a 48-year-old man who initially presented with calf discomfort and swelling. He was discharged with no anticoagulation after a negative complex duplex venous ultrasonography for deep vein thrombosis (DVT). He presented 4 days later with shortness of breath and pleuritic chest pain. Multiple pulmonary emboli were found on CT pulmonary angiogram. His ECGs showed left-ventricular strain which is unusual for PE. He was anticoagulated and discharged. Despite presenting 2 days later with PE-related complications, he eventually recovered well.
