Electrode Position
Follow the physician’s instructions for electrode placement when available.
For ECG monitoring, electrodes are attached only on the chest to allow patient movement
and obtain continuous stable ECG. The following leads are examples. When also monitoring
respiration, refer to the “Electrode Position for Respiration Monitoring” section.
and obtain continuous stable ECG. The following leads are examples. When also monitoring
respiration, refer to the “Electrode Position for Respiration Monitoring” section.
NOTE
The optimum electrode positions for ECG measurement are not always optimum for
respiration measurement. Select positions that are suitable for both ECG and respiration
measurement or positions which give priority to either ECG or respiration measurement.

Electrode Positions for ECG Monitoring
Six Electrodes
The 6-electrode method with lead II and lead V5 is effective for monitoring myocardial ischemia.
You can improve monitoring accuracy considerably by adding lead V4 to this combination.
Va and Vb can be at any position of the standard 12 leads V1 to V6, but V4 and V5 are most
appropriate for myocardial ischemic monitoring.
