The most important thing that has happened in the pre-hospital care of patients with acute pain/discomfort in the chest is the introduction of the pre-hospital electrocardiogram (ECG), i.e., the opportunity to take an ECG in the ambulance. However, knowledge of how electrocardiographic communication between the ambulance care and the receiving hospital is to be optimized still remains unclear.
The directing of patients straight from the ambulance to the treatment unit without passing through the casualty department means a more efficient chain of care. This operation requires constant review in order to be optimized.
The study tests the hypothesis that we can identify the patient groups which benefit most from being admitted directly to the Myocardial Infarction Department/Angiography lab through information from a quality registry for the patient group transported by an ambulance that had sent an ECG.
