How do you place a 12 lead ECG electrode?
Two. So the first rib is up high under the clavicles. This is rib number two the inner space just below it is the second intercostal.
Where do you put the 12 leads?
Simple steps for the correct placement of electrodes for a 12 lead ECG/EKG:
- Prepare the skin.
- Find and mark the placements for the electrodes:
- First, identify V1 and V2.
- Next, find and mark V3 – V6.
- Apply electrodes to the chest at V1 – V6.
- Connect wires from V1 to V6 to the recording device.
- Apply limb leads.
When applying electrodes for a 12 lead ECG Where should the V1 lead be placed?
Proper 12-Lead ECG Placement
| ELECTRODE | PLACEMENT |
|---|---|
| V1 | 4th Intercostal space to the right of the sternum |
| V2 | 4th Intercostal space to the left of the sternum |
| V3 | Midway between V2 and V4 |
| V4 | 5th Intercostal space at the midclavicular line |
Where should ECG electrodes be placed?
Regardless of a patient’s sex, the positioning of the electrodes remains the same: V1 and V2 flank the sternal borders at the fourth intercostal space; V4, V5, and V6 align starting at the fifth intercostal space; and V3 goes on the midway point between V2 and V4.
How many electrodes are needed for a 12 lead ECG?
Although it is called a 12-lead ECG, it uses only 10 electrodes. Certain electrodes are part of two pairs and thus provide two leads. Electrodes typically are self-adhesive pads with a conducting gel in the centre.
How do you identify intercostal spaces?
From the angle of Louis, move your fingers to the right and you will feel a gap between the ribs. This gap is the 2nd Intercostal space. From this position, run your fingers downward across the next rib, and the next one. The space you are in is the 4th intercostal space.
Does ECG lead placement matter?
Conclusions: We provide better and more robust evidence that routine modification of limb electrode placement produces only minor changes to the ECG waveform in healthy subjects. These are not clinically significant according to the 2009 guidelines and thus have no effect on the clinical specificity of the 12 lead ECG.
How do you remember lead placement?
5 Lead EKG Placement – Get it right every time! – YouTube
Where is V1 lead placed?
4th intercostal space
V1 – placed in the 4th intercostal space, right of the sternum. V2 – placed in the 4th intercostal space, left of the sternum.
Why does a 12-lead ECG have 10 electrodes?
Put simply, a lead is like a perspective. In 12-lead ECG, there are 10 electrodes providing 12 perspectives of the heart’s activity using different angles through two electrical planes – vertical and horizontal planes.
What is the main purpose of a 12-lead ECG?
The 12-lead EKG provides more information on the diagnosis of your cardiac arrhythmia than an outpatient Holter or Event monitor, as it represents information recorded from a larger surface area surrounding the heart.
How much space should be between ribs?
The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.
…
| Intercostal space | |
|---|---|
| TA2 | 1102 |
| FMA | 12243 |
| Anatomical terminology |
At what level is the sternal angle?
It is at the level of the intervertebral disc between thoracic vertebrae 4 and 5. This is the superior extent of the heart as well as the inferior end of the trachea when a person is supine.
Can you put ECG leads on the back?
The leads are placed on the back directly opposite of their typical anterior position. The limb leads retain their left-right direction. Lead V1 is to the right of the spine.
What can you not place ECG electrodes over why?
Avoid placing electrodes over tendons or major muscle masses. Attach the lead wires to the electrode before placing it on the patient’s chest. As you peel the electrode from its protective cover, insure the conducting gel is intact.
How do you read a 12-lead?

How many electrodes are needed for a 12-lead ECG?
What leads are V1 and V2?
The Chest Leads
The precordial, or chest leads, (V1,V2,V3,V4,V5 and V6) ‘observe’ the depolarization wave in the frontal plane. Example: V1 is close to the right ventricle and the right atrium. Signals in these areas of the heart have the largest signal in this lead.
What does V1 and V2 mean in ECG?
The areas represented on the ECG are summarized below: V1, V2 = RV. V3, V4 = septum. V5, V6 = L side of the heart. Lead I = L side of the heart.
What are the 3 types of ECG?
Types of ECG
a stress or exercise ECG – carried out while you’re using an exercise bike or treadmill. an ambulatory ECG (sometimes called a Holter monitor) – the electrodes are connected to a small portable machine worn at your waist so your heart can be monitored at home for 1 or more days.
What does V1 V2 V3 mean in ECG?
Which ECG lead is most important?
The most useful lead is V4R, which is obtained by placing the V4 electrode in the 5th right intercostal space in the mid-clavicular line.
How many pairs of ribs are considered false ribs?
There are three pairs of false ribs. They are intermediate between the true ribs and the floating ribs. They are sometimes called vertebrochondral ribs. They differ from the true ribs because they do not directly articulate with the sternum.
How do you realign your ribs?

Why is sternal angle important?
The sternal angle is an important clinical landmark for identifying many other anatomical points: It marks the point at which the costal cartilages of the second rib articulate with the sternum. This is particularly useful when counting ribs to identify landmarks as rib one is often impalpable.
