Post-Arrest ECGs That You Gotta Know

Feb 4, 2025
Dr. Amal Mattu, a leading expert in acute care medicine and cardiology from the University of Maryland, shares invaluable insights on post-arrest ECG interpretation. He emphasizes the dangers of misreading early ECGs, particularly the risks associated with VTach mimics. Listeners will learn when to repeat ECGs and when to refer patients for catheterization. Dr. Mattu also discusses life-threatening conditions like hyperkalemia and sodium channel toxicity that can look like VTach. His real-case examples make the discussion both practical and engaging.

Quick takeaways

  • Proper interpretation of post-arrest ECGs is crucial, as misdiagnosing dysrhythmias can lead to dangerous treatment decisions and patient harm.
  • Repeating the ECG around twenty minutes post-resuscitation allows for more accurate assessments, which can significantly impact patient management strategies.

Importance of Post-Arrest 12-Lead ECG

The post-arrest 12-lead ECG is critical for identifying ischemia, particularly distinguishing between ST-Elevation Myocardial Infarction (STEMI) and non-ST elevation conditions. When a patient presents with post-arrest symptoms and has restored pulses, determining if a STEMI is present can dictate immediate transfer to the catheterization lab. Conversely, if there is no evidence of STEMI, recent studies suggest that immediate catheterization may not be necessary, allowing for medical management instead. The CoACT trial and other recent literature emphasize that patients without ST elevation might benefit from delays in catheterization, highlighting the importance of careful ECG interpretation in emergency contexts.
