Rare but not forgotten: Case series of pulmonary embolism with S1Q3T3 pattern

Abstract

Pulmonary embolism (PE) is a common acute cardiovascular disorder. The most common electrocardiograph (ECG) finding in PE is sinus tachycardia. However, the S1Q3T3 pattern of acute cor pulmonale also called McGinn-White sign is classic. We report three cases of a 48-year-old man, 41-year-old woman, and a 66-year-old woman diagnosed with PE with the ECG findings of S1Q3T3 pattern. In conclusion, recognizing these ECG findings could prompt clinicians to consider PE and lead to earlier diagnosis.
