Assessment of the standardized reporting guidelines ECG classification system: the presenting ECG predicts 30-day outcomes.

Study Objective: Standardized reporting criteria for risk stratification studies of patients with potential acute coronary syndromes have been proposed. We sought to determine whether the categories in the recommended 6-item ECG classification system predict rates of 30-day death, myocardial infarction, and revascularization.

Methods: We conducted a prospective cohort study of emergency department (ED) chest pain patients who presented to a tertiary care center during a 32-month period.
