TIMING OF ELECTROCARDIOGRAPHIC DIAGNOSIS IN ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION PATIENTS WITH AN INITIAL NON-DIAGNOSTIC ELECTROCARDIOGRAM: AN OBSERVATIONAL ANALYSIS FROM THE NCDR®

Patients ultimately diagnosed with STEMI often have a non-diagnostic initial ECG. However, data to support the timing of follow-up ECGs in patients being evaluated for ACS are lacking. We aimed to describe the timing of ECG diagnosis in STEMI patients with an initial non-diagnostic ECG. We
