The goal of this clinical trial is to compare the result from the a six-leads handheld electrocardiogram (ECG) recorder (KardiaMobile 6L) with those of the standard 12-leads ECG at the patients of acute inferior wall ST-elevation myocardial infarction (STEMI), then ultimately reduce the time it takes to perform re-through treatment according to the faster diagnosis. Participants with STEMI who visited the emergency room will be recorded 6-leads ECG using KardiaMobile 6L in addition to the standard 12-lads ECG, which is basically performed for all patients of acute coronary syndrome.
