Abstract:
The prominent T wave is an abnormal T-wave morphology encountered in the earliest phase of ST-segment elevation acute myocardial infarction (AMI). Prominent T waves, however, are associated with other diagnoses, including hyperkalemia, early repolarization, and left ventricular hypertrophy (LVH). This article focuses on the electrocardiographic differential diagnosis of the prominent T wave with the presentation of 4 illustrative cases. We also recommend that the designation hyperacute should refer exclusively to the prominent T waves of ST-segment elevation AMI.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
