CET Holter Monitoring and Ambulatory EKG

Question 1

What is the typical recording duration for a standard Holter monitor?

Accepted Answer

24 to 48 hours

Answer

A standard Holter monitor records cardiac activity continuously for 24 to 48 hours to capture intermittent arrhythmias that may not appear on a brief resting EKG.

Question 2

What is the primary purpose of Holter monitoring?

Accepted Answer

To detect intermittent cardiac arrhythmias not seen on a resting EKG

Answer

Holter monitoring is used primarily to detect intermittent arrhythmias that may not occur during a brief resting 12-lead EKG.

Question 3

Which type of electrodes are used in Holter monitoring?

Accepted Answer

Disposable adhesive silver/silver chloride electrodes

Answer

Disposable adhesive silver/silver chloride electrodes are used in Holter monitoring because they provide reliable skin contact for extended recording periods.

Question 4

What is the main purpose of the patient diary in Holter monitoring?

Accepted Answer

To correlate patient symptoms and activities with the cardiac recording

Answer

The patient diary allows the interpreting physician to correlate reported symptoms and activities with corresponding cardiac events captured on the recording.

Question 5

Before attaching Holter monitor electrodes, the technician should prepare the skin by:

Accepted Answer

Cleaning, drying, and lightly abrading the skin
