How Do You Place Holter Monitor Leads?
When attaching Holter monitor leads to a patient, place the white lead on the sternum’s right manubrial border, place the red lead on the left anterior axillary line at the sixth rib, and position the black lead on the sternum’s left manubrial border, advises Advanced Cardiac Monitoring. Locate the xiphoid process, and position the brown lead around 1 inch to its right.
Position the blue lead to the center of the manubrium, and position the orange lead to the left midclavicular line of the sixth rib, reports Advanced Cardiac Monitoring. Finally, place the green lead on the lower right rib margin over the bone. When properly placed, the seven color-coded wires attached to the Holter monitor create a three-dimensional echocardiogram recording useful for diagnosing cardiac issues.
Because abnormal heart rhythms come and go, it is often difficult for doctors to diagnose them, notes Healthline. A patient exhibiting symptoms of irregular heartbeat wears a Holter monitor continuously for 24 hours as he goes through his normal daily routine. The monitor records his heart rhythm, and the doctor analyzes the data at the end of the 24-hour period to look for irregularities and determine whether there are delays in the heart’s electrical impulses and if the heart receives adequate oxygen. Doctors often order Holter monitor testing when patients complain of racing, skipping or irregular heartbeats or dizziness and fainting.
