¹Percentage calculated based on the total number of cases in each category;

²Percentage calculated based on the total number of cases in the study (250);

³Only cases with ST segment depression as the main finding;

⁴Only cases with T wave changes as the main finding, does not include T wave changes accompanying ST segment elevation or ST segment depression;

⁵Only 3 cases that were not T wave inversions.
