the quest says all symp of MI .
ECG--> Q waves in III and aVF, 2mV ST dep in leads V3 to V6, and 1mV ST segment elevation in V1.
though I understand various ECG changes and infarct location they denote, here in explaination they say that the ECG is 'nondiagnostic" I want to know when do we label an ECG to be nondiagnostic?

thanks

During the first 2 hr of MI ECG could normal. Is this the point?

1. The eKG is non-diagnostic because Q wave represents old infarct,

2. 1 mm elevation does not count, you need 2 mm 2 small box to show there is an infarct !
