The World Health Organization (WHO) defines pneumonia as a form of acute respiratory infection that affects the lung parenchyma and oxygenation. Diagnosis is based on clinical appearance confirmed by a chest X-ray (CXR) showing consolidation. The authors describe a patient who presented with a chief complain of an attack of dizziness and near syncope. Patient presented with headache, low-grade fever, non-productive cough and chest tightness. He was tachycardic with normal blood pressure and oxygen saturation (O2Sat) 97%. His ECG Showed S1Q3T3 pattern with a concern for pulmonary thromboembolism (PE) which prompt obtaining chest CT scan with IV contrast didn’t reveal pulmonary thromboembolism but showed a right-sided consolidation. Patient’s EKG findings resolved after treating pneumonia. This case demonstrates the cardiac electrographic findings of S1Q3T3 can be seen in patients with lobar pneumonia. 1. Stein PD. Matta F.
