Electrocardiogram

Pulmonary embolim:

• Sinus tachycardia 
• Complete or incomplete RBBB 
• Right ventricular strain pattern 
  • T wave inversions in the right precordial leads (V1-4) ± the inferior leads (II, III, aVF). This pattern is associated with high pulmonary artery pressures.
• Right axis deviation
• Dominant R wave in V1
  • Shows the manifestation of acute right ventricular dilatation.
• Right atrial enlargement (P pulmonale)
  • Peaked P wave in lead II > 2.5 mm in height
• Atrial tachyarrhythmias
  • AF
  • Flutter
  • Atrial tachycardia
• Non-specific ST segment and T wave changes, including ST elevation and depression.

Libman-Sacks endocarditis:

• Sinus tachycardia
