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.

Before coronary angiography, all participants will contact both fingers on the two probes at the front side of portable 6-leads electrocardiogram recorder (KardiaMobile 6L), and be recorded all six leads by contacting the other side of probe at lower extremities (left hip bone ridge, thigh, knee, lower abdomen, etc.).

RECRUITINGHeight (amplitude) of the ST segment of lead II, III and aVF at portable 6-leads electrocardiography (ECG) from KardiaMobile 6L before coronary angiography (CAG)
Height (amplitude) of the ST segment of lead II, III and aVF at portable 6-leads ECG obtained using KardiaMobile 6L between the ER visit and performing emergent CAG (experimental group) or between the admission and elective CAG (control group).
Time frame: pre-intervention
