Overview

Tombstone ST elevation is a particular electrocardiographic pattern of ST segment elevation that 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.
