Which of the following ECG changes is one of the earliest to occur during an ST-elevation infarction, but may have resolved by the time the patient seeks medical assistance?

b. Hyperacute T waves
c. Horizontal ST-segments
d. Lengthening of the QT interval


B
Hyperacute (i.e., tall) T waves are sometimes called tombstone T waves and typically measure more than 50% of the preceding R wave. In addition to an increase in height, the T wave becomes more symmetric and may become pointed. These changes are often not recorded on the ECG because they have typically resolved by the time the patient seeks medical assistance.
