12 Lead ECG
Steps
Performed?
Yes No
1.
Prepare ECG monitor and connect patient cable with electrodes.
☐
☐
2.
Enter the required patient information into the 12-Lead ECG device.
First and Last Name
Date of Birth
Age
Gender
Cardiologist (if able to enter)
☐
☐
3.
Expose chest (respecting modesty) and prep as necessary.
Poor quality can be caused by lack of skin preparation. Use a gauze pad to vigorously rub the
site, to remove the outer layer of dead skin. Dry the site. Alcohol preps can remove creams or
lotions. Remove excess hair as needed.

☐
4.
Attach limb leads on or near the limbs. Avoid attaching to the torso.
Attaching leads to the torso produces a cleaner rhythm, but may limit evaluation of ECG. Some
changes that may occur are:
Cardiac axis shift to the right
R wave becomes smaller in Lead I
Less prominent Q waves in inferior leads
☐
☐
5.
Apply chest leads and extremity leads using the following landmarks:
☐
☐
RA – Right arm
LA – Left arm
RL – Right leg
LL – Left leg
V1 – 4
th
ICS at sternal border
V2 – 4
th
ICS at sternal border
V3 – Directly between V2 and V4
V4 – 5
th
ICS at midclavicular line
V5 – Level with V4 at anterior axillary line
V6 – Level with V5 at midaxillary line
6.
Instruct patient to remain still.
☐
☐
7.
Press the appropriate button to acquire the 12-Lead ECG.
☐
☐
8.
If the provider is an EMT or AEMT without a Paramedic present, transmit the 12-Lead.
If a Paramedic is present and the 12-Lead shows STEMI or a life threatening
arrhythmia, transmit to the receiving facility.
If the Paramedic identifies a STEMI, activate the cath lab by calling the receiving facility
and identifying your unit, then stating “I have a STEMI.” Then explain the situation,
including the leads with ST elevation, and verbally activate the cath lab.
9.
If the tracing displays too much artifact, consider the following:
☐
☐
Check cable connection
Is the equipment functioning properly?
Is there interference from external
electrical equipment?
Are the electrodes dry?
Is there poor adhesion?
Are the cables touching a metal surface?
Are the cables entangled or hanging?
Is the snap connection secure?
10. Monitor the patient while continuing with the treatment protocol.
