    • A 47 year old woman with recent history of upper respiratory infection for a week, comes to the emergency room complaining of chest pain. She describes the pain in the middle of her chest, constant, non-radiating and has been going on for the last day. She said that the pain gets worse when she takes deep breathes, but improves when she leans forward. She is afebrile at this time, with a heart rate of 112bpm, and blood pressure of 135/95. An ECG is ordered, demonstrating ST segment elevations in all leads. What is the most likely diagnosis in this patient?

    USMLE Step 1

    • Kardia (Greek) - Heart
    • Nervus (Latin) - Sinew, tendon; cord, bowstring

  • Pericardiocentesis

    A procedure in which the area "around" the "heart" is "punctured" in order to extract and sample fluid

  • This procedure is generally used to relieve pericardial effusions, the buildup of fluid in the pericardium (the sac around the heart). It is also used in emergent situations with cardiac tamponade, where the fluid builds up too rapidly causing compression on the heart impairing its pumping action.
