Acquiring a 12-Lead ECG
Intended Use
The 12-lead ECG offers paramedics and emergency physicians significant advantages over the
single lead ECG trace typically available in EMS. The 12-lead ECG not only provides a
diagnostic quality ECG for use in the detection of ST elevation myocardial infarction (STEMI), but
also allows the knowledgeable paramedic to determine the area of myocardial injury, anticipate
associated potential complications, and implement treatment strategies accordingly. In addition,
the 12-lead ECG provides a baseline for serial ECG evaluations.
The 12-lead ECG transmission to the emergency department (ED) is recommended by the AHA
and ERC for patients with Acute Coronary Syndrome (ACS). When transmitted from the field,
12-lead ECG has been shown to shorten time to in-hospital treatment by an
estimated 10 to 60 minutes. Patients may also benefit from triage and transport to the most
appropriate facility. Documentation of transient or intermittent arrhythmias and other
electrophysiologic events that occur in the prehospital setting can assist in diagnosis and
treatment decisions in the ED.
Indications
The 12-lead electrocardiogram is used to identify, diagnose, and treat patients with cardiac
disorders and is useful in the early detection and prompt treatment of patients with acute ST-
elevation myocardial infarction (STEMI).
Contraindications
None known.
12-Lead ECG Warning
Possible Inability to Obtain a Diagnostic 12-lead
ECG
Using previously unpackaged electrodes or electrodes
past the Use By date may impair ECG signal quality.
Remove electrodes from a sealed package immediately
before use and follow the procedure for applying the
electrodes.
Identifying Electrode Sites
To obtain a 12-lead ECG, place the electrodes on the limbs and the chest (precordium) as
described in the following paragraph.
