Overview

An ECG may be helpful in the diagnosis of tuberculous pericarditis. Findings on an ECG suggestive of tuberculous pericarditis include:[1][2][3][4]

  • Low voltage QRS
  • Absence of ST segment elevation which we usually see in acute pericarditis
  • Inverted T wave
  • Atrial fibrillation
  • Electrical alternans
