Would you be concerned? Does this patient need the cath lab?

These are definitely hyper acute T waves and areĀ considered a STEMI-equivalent.
Koechlin L et al(1) conducted a post hoc analysis Ā of a multicenter diagnostic study and looked at the diagnostic performance of T wave amplitude for diagnosing myocardial infarction. They found that they were not useful in making this diagnosis.
One of the concerns is that they only looked at T wave amplitude. Smith(2) states that more than just amplitude is important to make the diagnosis. He refers to the T-wave ābulkā The T wave is large in area, symmetric relative to the QRS.
The term ā T wave towersā over the R wave in V3, or even that the QRS can fit into the T wave are important in terms of this ābulkā.
