Beginner ECG 15

  1. Sinus tachycardia
  2. Anterior myocardial infarction
  3. Hyperacute T wave abnormality

Many different T wave abnormalities exist. Hyperacute T waves are the very first sign of a myocardial infarction, however are frequently missed on the ECG since they are only transient during the first few minutes of the infarction. Hyperacute T waves tend to be a bit more symmetric and broad at the top than those "peaked" T waves seen in hyperkalemia, although this is difficult to distinguish at times. On this ECG, the ST elevation gives away the fact that the T waves are hyperacute. Some different T wave abnormalities are pictorally shown below:
