Acute coronary syndromes: 2b-ECG performed within 10 minutes of arrival of ambulance
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||Indicator 2b-ECG performed within 10 minutes of arrival of ambulance|
|Registration status:||Health, Standard 12/09/2016|
Proportion of patients with chest pain with a 12-lead electrocardiogram (ECG) performed within 10 minutes of first clinical contact, after arrival of ambulance.
Early diagnosis optimises door-to-needle time and time to other interventions. The time taken to record the first ECG is a good index of quality care. The European Society of Cardiology guidelines identify that ECG should be performed within ten minutes or less after the first clinical contact (either on arrival of the patient in the emergency department or at first contact with emergency medical services in the pre-hospital setting) and immediately interpreted by a qualified physician (Steg et al. 2012; Hamm et al. 2011).
