Time to ECG diagnosis delays inter-hospital transfer to revascularization in STEMI patients presenting to a regional emergency department: a five-year audit.

Nearly half of the patients studied failed to achieve the overall target D2BT for revascularization. The time from arrival at the CHB ED to diagnostic ECG was identified as a substantial contributor to this failure, with a median time almost twice that of the target and a quarter of all patients spending longer than 46.8 min. These findings highlight a need to improve the implementation of ECG triage and interpretation in the ED.
