Transmit the ECG to the receiving facility. If multiple 12-leads are obtained, transmit the one(s) that influenced your treatment decision(s).
The 12-lead monitor (when available) should routinely be carried in to the patient’s house upon EMS arrival and a 12-lead should be obtained (for these patients) as soon as possible (goal = within 10 minutes of first medical contact).
