Once all electrodes have been applied, attach the associated limb leads, with the cable for each lead lying inferior to the electrode (to reduce tension on the wire). Some people find the mnemonic “Ride Your Green Bike ” useful for remembering the placement of the limb leads, starting clockwise from the right wrist.

Shave hair that can possibly impede electrode placement. Electrodes should have full contact with the patient's skin. For better electrode adhesion and oil-free skin, rub the area with an alcohol prep pad or gauze paid with benzoin tincture.
How many transverse leads are there in the heart?
By using 6 chest electrodes, you get 6 transverse leads that provide information about the heart's horizontal plane: V1, V2, V3, V4, V5, and V6. Like the augmented leads, the transverse leads are unipolar and requires only a positive electrode. The negative pole of all 6 leads is found at the center of the heart.

Since the first telecardiogram recorded in 1903 , huge strides have been made in the recording and interpretation of ECG. Today, the 12-Lead ECG remains a standard diagnostic tool among paramedics, EMTs, and hospital staff.
What is a F-ECG?
Fontaine bipolar precordial leads (F-ECG) are used to increase the sensitivity of epsilon wave detection. Named after French cardiologist and electrophysiolgist Guy Hugues Fontaine (1936-2018). Leads are placed as shown:

Posterior leads. Leads V7-9 are placed on the posterior chest wall in the following positions: V7 – Left posterior axillary line, in the same horizontal plane as V6. V8 – Tip of the left scapula, in the same horizontal plane as V6. V9 – Left paraspinal region, in the same horizontal plane as V6. See Posterior STEMI.
Which bipolar leads record the atrial potentials?
Instead of regular leads I, II, and III there are now three bipolar chest leads that are termed FI, FII, and FIII which record the potentials developed in the right ventricle, from the infundibulum to the diaphragm. The vertical bipolar lead FI, (similar to aVF) magnifies the atrial potentials and can be used to record:
What is Lewis lead?
Lewis lead (S5-lead) The Lewis lead configuration can help to detect atrial activity and its relationship to ventricular activity. Named after Welsh cardiologist Sir Thomas Lewis (1881-1945) who first described in 1913. Useful in: Observing flutter waves in atrial flutter.
What is the most useful investigation in medicine?
The ECG is one of the most useful investigations in medicine. Electrodes attached to the chest and/or limbs record small voltage changes as potential difference, which is transposed into a visual tracing
What is the 12 lead EKG?
The 12-lead ECG electrode placement is essential for paramedics and EMTs in both prehospital and hospital setting as incorrect placement can lead to false diagnosis of infarction or negatively change the EKG.
Where to put limb leads?
Limb leads can be placed on any part of the patient’s respective limbs. Just make sure the leads are symmetrical. For example, don’t put one lead on the left shoulder and the other lead on the right forearm. I’ve heard of one local doctor that preferred all 4 leads to be placed relatively equal distances distally.
What is an ECG?
An ECG stands for electrocardiogram. It is a tool used to detect a wide range of heart dysrhythmias using waveforms on a monitor. It is used by healthcare providers regularly both in the hospital and by EMS.
How to relax a patient's shoulders?
Place the patient’s arms down by their side to relax their shoulders. Patient’s legs should be uncrossed. Electrical devices such as mobile phones should be away from the patient as these devices may interfere with the machine. Dry the skin if it is diaphoretic or moist.
How many leads are there in the heart?
A lead is a view of electrical activity of the heart from a specific angle across the body. So, even though you only have 10 leads, you are actually getting 12 views from different angles.
Where should lead V4 be placed?
At a minimum, lead V4 should be placed on the 5th intercostal, mid-clavicular (exact opposite of the regular left side placement) if an inferior infarct was originally seen in leads II, III, and AVF. These give you more views of the heart and can help inform your treatment plans.
Can you use electrode gel over bones?
Shave any hair that can interfere with electrode placement. Electrode gel should be moist. Electrodes should not be placed over bones and over areas where there is a lot of muscle movement. Sometimes an abrasive material such as a wash cloth may need to be used to remove dead skin cells.
Best Practices for ECG Lead Placement on Women
As with any diagnostic tool, accurate utilization of ECG is critical—and that includes correct ECG lead placement on women and men. As a paper in Circulation notes, misplacements can lead to incorrect readings of waveforms, potentially causing false-positive or false-negative diagnoses of conditions such as arrhythmias or myocardial infarction.
ECG Lead Placement on Women: Nuances to Understand
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.
Ensuring Equitable Care Through Practice and Training
Variances in electrode placement between male and female patients can delay critical care and ultimately impact patient outcomes. ECG professionals should remain wary of potential lead misplacement and work to implement the correct positioning by using bone landmarks.

The negative pole of all 6 leads is found at the center of the heart. This is calculated with the ECG.
Why does my electrode gel dry out?
Often, electrode gel dry-out is a result of incorrect storage. Store electrodes as instructed by manufacturer and do not remove from their pouch until they’re ready for use. Do not place electrodes on skin over bones, incisions, irritated skin, and body parts where there is lots of possible muscle movement.
What is a 12 lead ECG?
12-Lead ECG Placement. The 12-lead ECG is a vital tool for EMT’s and paramedics in both the prehospital and hospital setting. It is extremely important to know the exact placement of each electrode on the patient. Incorrect placement can lead to a false diagnosis of infarction or negative changes on the ECG.
What are the two types of ECG leads?
The ECG leads are grouped into two electrical planes. The frontal leads (Lead I-III, aVR-F) view the heart from a vertical plane, while the transverse leads (V1-V6) view the heart from a horizontal plane.
What is lead in medical terms?
A lead is a view of the electrical activity of the heart from a particular angle across the body. Think of a lead as a picture of the heart and the 10 electrodes give you 12 pictures.
Can a 12-lead ECG have an artifact?
The heart’s electrical signal is very small and unfortunately this can be combined with other signals of similar frequency to create artifact. It’s not uncommon for 12-lead ECG’s to have some form of artifact; however, it’s important to try to reduce any interference to ensure an accurate ECG.
Limb electrode and lead placement
Apply the four limb electrodes on a distal bony prominence in the following locations:
