CCT - Certified Cardiographic Technician Ambulatory (Holter) Monitoring Questions and Answers

Question 1

A patient undergoing Holter monitoring is instructed to keep a diary. What is the primary purpose of this diary?

Accepted Answer

To correlate the patient's symptoms with the ECG recording.

Answer

The patient diary is a critical component of ambulatory monitoring. By recording the exact time and nature of symptoms like dizziness, palpitations, or chest pain, the physician can correlate these subjective feelings with the objective ECG data recorded at that precise moment.

Question 2

A patient calls the clinic stating that their Holter monitor is beeping intermittently. They have checked the battery, and it appears to be fine. Which of the following is the most likely cause?

Accepted Answer

A poor or detached electrode connection.

Answer

Intermittent beeping from a Holter monitor, especially when the battery is not the issue, most commonly indicates a problem with the signal acquisition, such as a loose or completely detached electrode. This breaks the electrical circuit, and the device alerts the user to the faulty connection.

Question 3

Which of the following instructions is most critical for a CCT to provide to a patient being fitted for a standard 24-hour Holter monitor?

Accepted Answer

Refrain from bathing or showering while wearing the device.

Answer

Holter monitors are electronic devices that are not waterproof. It is essential to instruct the patient to avoid showering, bathing, or swimming to prevent water damage to the monitor and to ensure the electrodes remain securely attached to the skin.

Question 4

Ambulatory Holter monitoring is particularly effective for diagnosing which of the following conditions?

Accepted Answer

Intermittent or paroxysmal arrhythmias.

Answer

The primary utility of a Holter monitor is to capture ECG data over an extended period (typically 24-48 hours), which significantly increases the chance of detecting arrhythmias that are sporadic, infrequent, or occur only with specific triggers, which would likely be missed by a standard 10-second ECG.

Question 5

While reviewing a 24-hour Holter recording, a technician notes several periods of significant baseline wander and artifact, making interpretation difficult. Which of the following is a common cause of this type of artifact in an ambulatory setting?

Accepted Answer

Poor electrode-to-skin contact.

Answer

Poor electrode adhesion or contact with the skin is a very common cause of baseline wander and artifact on both resting and ambulatory ECGs. Patient movement, sweat, or inadequate skin preparation can cause the electrodes to lift slightly, disrupting the stable electrical connection needed for a clean tracing.
