Ambulatory cardiac monitoring options include which of the following?

• A. Holter device
• B. All of the above
• C. Implantable loop recorder
• D. Mobile cardiac telemetry

Answer: (B)

Ambulatory cardiac monitoring covers devices used to record heart rhythm outside the clinic over different timeframes. The Holter monitor is a wearable recorder worn for about 24 to 48 hours to capture continuous rhythm data. An implantable loop recorder is placed under the skin and can monitor heart rhythms for months or even years, which is helpful when symptoms are rare. Mobile cardiac telemetry uses a wearable sensor that transmits data to a monitoring center, providing longer-term observation with real-time or near-real-time alerts.

Since each of these options fits the idea of evaluating heart rhythm outside the hospital, all of the listed modalities are ambulatory monitoring options.
