A young man presented with acute stabbing chest pain. A 12-lead electrocardiogram revealed electrical alternans with phasic variation of the QRS amplitude in all leads. Lung auscultation revealed absent left hemithorax breath sounds. Chest radiography confirmed a left-sided tension pneumothorax. Ten...

Description
Summary:A young man presented with acute stabbing chest pain. A 12-lead electrocardiogram revealed electrical alternans with phasic variation of the QRS amplitude in all leads. Lung auscultation revealed absent left hemithorax breath sounds. Chest radiography confirmed a left-sided tension pneumothorax. Tension pneumothorax is a very rare cause for electrical alternans.
