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.
NOTE: The Right Leg (RL) electrode may be positioned in any location least subject to motion artifact
according to clinician preference and specific test requirements.
