Why you should read this article:

  • To acknowledge the importance of recording a 12-lead electrocardiogram (ECG) in the assessment and diagnosis of patients with suspected arrhythmias, hypertension, coronary heart disease or heart failure

  • To optimise your practice when recording a 12-lead ECG, including correct positioning of the electrodes and appropriate patient preparation

  • To understand the evidence base that supports the practice of recording a 12-lead ECG

Rationale and key points

This article provides a step-wise, practical approach to recording a 12-lead electrocardiogram (ECG) and explores the evidence base that supports the use of this important assessment tool in clinical practice.

A 12-lead ECG is frequently used in a variety of clinical settings, including emergency care, preoperative and post-operative assessment, and primary care. It is used to assess and diagnose patients with suspected arrhythmias, hypertension, coronary heart disease or heart failure.

Correct positioning of the electrodes using anatomical landmarks is essential to ensure an accurate and high-quality ECG recording.

Skin preparation is essential, since suboptimal electrode contact or electrodes being placed where there is a significant amount of dry or dead skin cells, grease, sweat or hair, can negatively affect the quality of the ECG recording.

As a nursing student and new nurse, I had trouble remembering where to place electrodes (RA, RL, LA, LL, V1, V2, V3, V4, V5 & V6) on a patient for a 12 lead EKG. However, after much practice I have finally got it. In this article, I want to prepare you for how to place electrode stickers on a patient for a 12 lead ECG (EKG) so you will be prepared in clinicals and as a new nurse.  In addition, I’m going to demonstrate how to place  electrodes for a 12 lead ECG in a video tutorial.

In the hospital and clinic setting, you will be expected to obtain a 12 lead EKG on a patient. This is done at the bedside with a machine. The machine analyzes various angles of the heart and interprets the patient’s heart rhythm and rate.

You can tell so much about a patient’s cardiac status from an EKG. For instance, if a patient is having chest pain, you can look at an EKG and tell if they are having an active myocardial infraction (in most patients). In addition, you can tell if they are in any type of abnormal rhythm such as atrial fibrillation or atrial flutter etc.

Supplies you will need

  • 10 Electrode Stickers
  • 1 strip of abrasive tape (this roughs up the epidermis so you can get a good connection)
  • Alcohol prep pads (cleans the skin’s oils so you can get a good connection)
  • Hair Trimmers (used to remove excessive hair on men)

Prep the Skin

First clean the electrode site placements with alcohol prep to remove oils and dirt from the skin. Then gently “rough up” the area with the abrasive tape so the electrodes will stick properly.

Tip: Always make sure your electrodes are not expired or the gel is dry because this can affect the connection. In addition, never place an electrode over an implanted device in the skin.

There are a total of 10 leads (4 limb leads & 6 chest/precordial leads) and they are the following:

  • Right arm (RA)
  • Left arm (LA
  • Right leg (RL)
  • Left leg (LL)
  • V1
  • V2
  • V3
  • V4
  • V5
  • V6

Location of EKG 12 Lead Placement

  • RA: Placed on the right arm or right below the right clavicle
  • LA: Placed on the left arm or right below the left clavicle
  • RL: Placed on the right leg or upper right quadrant
  • LL: Placed on the left leg or upper left quadrant
  • V1: Placed in the fourth intercostal space to the right of the sternum
  • V2: Placed in the fourth intercostal space to the left of the sternum
  • V3: Placed directly between leads V2 and V4
  • V4: Placed in the fifth intercostal space in the mid-clavicular line
  • V5:  Placed level with V4 at the left anterior mid-axillary line
  • V6: Placed level with V5 at the mid-axillary line
