Can you help me interpret stress test finding?

Had a thallium stress, ECHO, and EKG.....what does it all mean?

THALLIUM STRESS TEST FINDING:"There is a tiny zone of nontransmural reversibility in the anteroseptal region. This is most likely an artifact. The left ventricle does not appear dilated. A small zone of iscehmia is not entirely excluded."

EKG report said: "Slight abnormality in T-wave in the inferior leads."

ECHO repaid said: "mild left atrial dilation." & "trace PI and MR with mild TR"
