However, errors in placement of ECG leads can create artifacts, mimic pathologies, and hinder proper ECG interpretation. One row starts with lead I, switches to aVR to be followed by V1, and ends with V4. December 2020. Emphysema, ECG lead placement: high lead placement may produce small R waves, either because the leads themselves are placed too high on the chest (or the leads are switched, eg V1 and V3), or because hyperinflation from emphysema lowers the diaphragm and heart. The white lead should be placed in the right part of the chest while the black lead is in the left part of the chest. A second row starts with lead II and records aVL, V2, and V5 in sequence while a third row records lead III, aVF, V3, and V6 in sequence.
