ECG Case 314 Interpretation

This post is an answer to the ECG Case 314

  • Rate: 108 bpm
  • Rhythm: Regular sinus rhythm
  • Axis:Normal
  • Intervals:
    • PR – Normal (160-180ms)
    • QRS – Normal
    • QT – 300ms
  • Segments:
    • Up-sloping ST segment in lateral precordial leads

  • Additional:
    • Prominent T waves in leads II, aVF, V6 (in relation to QRS magnitude)
    • Low QRS voltage
      • No electrical alternans
    • Baseline artifact affecting leads V4-6 and end of rhythm strip
ECG showing prominent T waves in leads II, aVF, V6 (in relation to QRS magnitude)

Interpretation

  • Prominent T waves in the setting of chest pain are concerning for OMI
  • Requires serial ECG’s looking for progressive ST segment change
  • Combination of low voltage and tachycardia should prompt consideration of pericardial effusion as a cause for the chest pain.
  • As with all ECG’s the ECG features need to be considered in the patient’s specific clinical context

What happened next ?

The patient was admitted for investigation under the cardiology team. Serial troponins and D-dimer were negative and an angiogram showed only minor vessel irregularities.
