CET Holter Monitoring and Ambulatory EKG 2

Question 1

Which lead configuration is most commonly used in two-channel Holter monitoring?

Accepted Answer

Modified bipolar leads resembling V1 and V5 positions (e.g., CM5 and CC5)

Answer

Modified bipolar leads resembling V1 and V5 positions are most commonly used because they provide effective arrhythmia detection and ST segment monitoring.

Question 2

A cardiac event monitor differs from a standard Holter monitor in that it:

Accepted Answer

Can be worn for weeks to months and records during symptomatic episodes

Answer

Unlike a Holter that records continuously for 24-48 hours, a cardiac event monitor is worn for weeks to months and records when triggered by patient symptoms or automatic arrhythmia detection.

Question 3

After Holter monitoring is complete and the patient returns the device, what should the technician do FIRST?

Accepted Answer

Inspect electrode sites for skin irritation and document findings

Answer

Patient safety comes first; the technician should inspect and document any skin reactions or breakdown at electrode sites before downloading data.

Question 4

For which condition would Holter monitoring be MOST clinically useful?

Accepted Answer

Paroxysmal supraventricular tachycardia (PSVT)

Answer

PSVT is ideal for Holter evaluation because it occurs unpredictably and briefly, requiring extended monitoring to capture the arrhythmia during a symptomatic episode.

Question 5

Heart rate variability (HRV) analysis from a Holter recording provides information primarily about:

Accepted Answer

Autonomic nervous system function and cardiovascular risk

Answer

HRV analysis measures the variation in time between consecutive heartbeats, which reflects autonomic nervous system tone and is a predictor of cardiovascular risk.
