Cardiac Subspecialty Certification (CSC) Exam

Answer: B - While wearing a Holter monitor, patients should maintain an activity diary so that any abnormality can be linked to this activity. Conversely, the diary may demonstrate that no abnormality occurs with certain activities. Patients should continue with prescribed medications and carry out normal activities since the primary purpose of a Holter monitor is to assist in diagnosis and to determine triggers for abnormal electrocardiogram readings. The monitor should be used during the night as some cardiac abnormalities may occur during sleep.
