AHA UA/NSTEMIのガイドライン

If the initial ECG is not diagnostic but the patient remains symptomatic and there is high clinical suspicion for ACS, serial ECGs, initially at 15- to 30-min intervals, should be performed to detect the potential for development of ST-segment elevation or depression. (Level of Evidence: B)

AHA STEMIのガイドライン

If the initial ECG is not diagnostic of STEMI but the patient remains symptomatic, and there is a high clinical suspicion for STEMI, serial ECGs at 5- to 10- minute intervals or continuous 12-lead ST-segment monitoring should be performed to detect the potential development of ST elevation. (Level of Evidence: C)

使い分けは難しい。。。。
5-10分で再検しましょう。その前に可能ならば循環器医を呼ぶことを、個人的には推奨です。
