Two types of mi: One type is st segment elevation (formally called Q wave mi ) and a non st segment (formally called non q ) mi . The difference between the two is the ekg. St segment on the ekg and an elevated blood level of cardiac enzymes is usually obvious. In the non st segment mi the ekg may be normal or mildly abnormal. The enzymes come back elevated but usually aft admission and a couple of blood sample.

Q vs. non-Q: When a heat attack causes a full thickness ("transmural") heart attack, the ekg reveals the resulting scar by inscribing a "q" wave in the leads that correspond to the damaged area. If the heart attack was not transmural or occurred in an area not seen well on ekg, there may be no q waves. If you had no symptoms at the time of the heart attack (25-50% of all attacks), it will be "unrecognized.".
