They are located in the 4th intercostal space, just right and left, respectively, of the sternum. It is fairly easy to determine this spot using the angle of Louis as a landmark.</p> <p>However, V1 and V2 were being misplaced pretty much right after being invented. This error in lead positioning usually produces trivial changes in the QRS pattern in those leads, and thus no real change in ECG interpretation. But certain erroneous ECG patterns can be generated, and it is important to recognize lead misplacement as a potential cause.</p>
