A 60-year-old man presented to the AED with intermittent chest pain of several days' duration. He could not recall the exact onset of the pain. His BP was 150/90 mmHg and SpO2 was 97% on room air.
Which of the following statement is correct?
Choose the correct answer.
The ECG showed ST-segment elevation in the Anterior leads (V2-4), consistent with an Anterior STEMI.
Although the exact onset time was unknown, it should not be treated as a delayed presentation because the chest pain was intermittent and persistent. Baseline ECG comparison is not mandatory for a diagnosis of STEMI, and overt reciprocal changes are not always present. Since obvious ST elevation was present on the initial ECG, serial ECGs are not necessary, thereby avoiding delay in revascularization
