Jones Chief Instructor, Medicus of Houston, Texas, USA 2022 04 22 As emergency physicians, we must all interpret electrocardiograms (ECGs) for time to time. The 12-lead ECG is one of the most frequently ordered tests in the emergency department, often read by physicians with the least formal training in ECG interpretation.
