PATIENT PREPARATION
28
NOTE AND CAUTION: Placement of the Left Leg (LL) electrode in the original Mason-Likar
position increases the similarity of the acquired ECG with a standard 12-lead ECG and is therefore
recommended; however, clothing may interfere with this position and increase the amount of artifact. The
modified position may decrease the sensitivity of inferior ECG leads and cause axis shift with respect to
the standard 12-lead ECG. Accurate skin preparation and suitable clothing are the most important factors
in excessive artifact prevention.
