84-year-old female OOHCA . ROSC but unfortunately suffered cardiac arrest shortly afterwards and died despite maximal resuscitative efforts. The post-ROSC ECGs below tell an important story. Thoughts ?#cardiotwitter#ecg #@smithECGBlog
This cardiac MRI shows a left atrium with a volume of ~2.2 liters.
For comparison:
🟢 Normal LA volume ≈ 22–58 mL
🔴 This LA ≈ 2200 mL
That's roughly 40–100× larger than normal.
A normal left atrium holds only a few tablespoons of blood. This one holds nearly the volume of a large soft drink bottle.
