HHIT,
thanks for the post.
There are a lot of thing that can cause changes in the ST portion of the ECG. That is why it's called nonspecific. We see it quite frequently so without nay other context it's ahrd to tell you too much. I would let the cardiologist take a look, in the mean time I wouldnt try to get too worked up about it as it is a rather common finding.
good luck
Nonspecific findings are often found on computer-interpreted EKG reports. Most times nothing is found to be wrong.
Your doctor is simply being appropriately cautious in referring you for furthur evaluation.
