EEG Ambulatory 2

Question 1

What is the typical recording duration for an ambulatory EEG study?

Accepted Answer

24-72 hours

Answer

Ambulatory EEG studies typically record for 24-72 hours, allowing capture of events that may not occur during a brief routine recording, including sleep-wake cycles.

Question 2

Which artifact is most commonly encountered in ambulatory EEG recordings compared to in-lab studies?

Accepted Answer

Movement and muscle artifact

Answer

Movement and muscle artifact are the most common artifacts in ambulatory EEG because patients are performing their normal daily activities, unlike the controlled laboratory environment.

Question 3

What electrode application method is preferred for ambulatory EEG to ensure electrodes remain in place during extended recording?

Accepted Answer

Collodion adhesive

Answer

Collodion is the preferred adhesive for ambulatory EEG because it provides secure, long-lasting electrode fixation that withstands the physical activity of daily living during multi-day recordings.

Question 4

What is the primary advantage of ambulatory EEG over inpatient video-EEG monitoring?

Accepted Answer

Recording in the patient's natural environment at lower cost

Answer

Ambulatory EEG allows recording in the patient's natural environment, capturing habitual events during normal daily activities at significantly lower cost than inpatient monitoring.

Question 5

What should an ambulatory EEG patient do when experiencing a suspected seizure or event?

Accepted Answer

Press the event marker button and keep an event diary

Answer

Patients are instructed to press the event marker button on the ambulatory device and record the event details (time, symptoms, activity) in their diary, enabling correlation of clinical events with EEG data.
