This electrocardiogram shows non-specific ST-T abnormalities. This term applies to many different variations in the ST segment and the T wave that do not suggest a specific diagnosis.

In this tracing, the T waves are flat in all leads. These non-specific abnormalities are observed in a large variety of clinical settings, including drinking cold water and hyperventilation, electrolyte disturbances and the effects of drugs.

Overall, these minor and non-specific changes suggest that a hemodynamically significant lesion could not have been present for long.
