Clinical Trial Summary

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.

Eligibility

Inclusion Criteria:

• Among the patients over 19-year-old, patients of ST-elevation myocardial infarction who visit the emergency room and perform emergency coronary angiography or

• Among the patients over 19-year-old, patients who visit outpatient clinics and perform elective coronary angiography for evaluating chest pain

Exclusion Criteria:

• Patients with severe complications of myocardial infarction; cardiogenic shock, respiratory failure and mental change

• Patients who are unable to agree or disagree a written consent

Related Conditions & MeSH terms

• Electrocardiogram
• Infarction
• Myocardial Infarction
• ST Elevation Myocardial Infarction

Intervention

Diagnostic Test:
• KardiaMobile 6L
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.).
