WebAdditional notes on 12-lead ECG Placement: The limb leads can also be placed on the upper arms and thighs. However, there should be uniformity in your placement. For instance, do not attach an electrode on the right wrist and one on the left upper arm. For female patients, place leads V3-V6 under the left breast. WebUnderstanding what the leads are viewing and if they are contiguous is as important in interpreting a 12-lead ECG as the changes that you will be looking for. Leads II, III and aVF are leads that have their positive electrode located at the left foot. They are contiguous leads that all look at the inferior wall of the left ventricle.
