Overview

Tombstone ST elevation is an electrocardiographic pattern of ST segment elevation whereby the QRS complex, the ST segment and the T wave merge to form a large upright monophasic deflection called a "tombstone"[1][2][3][4]. This electrocardiographic pattern has been associated with poorer clinical outcomes in the setting of ST segment elevation myocardial infarction.

Criteria

  1. The R wave is absent or its duration is <0.04 seconds with minimal amplitude;
  2. The ST segment is convex upward and merges with the descending limb of the R wave or the ascending limb of the QS wave;
  3. The peak of the convex ST segment is higher than whatever remains of the R wave; and
  4. The convex ST segment merges with the ascending limb of the T wave.
