Final answer:
During Holter monitoring, the assistant prepares and applies the monitor to the patient, ensures accurate data collection, and reviews the recorded data for abnormalities.
Step-by-step explanation:
The assistant plays a crucial role during Holter monitoring by preparing the patient, applying the Holter monitor, and ensuring accurate data collection.
First, the assistant explains the procedure to the patient, attaches the electrodes to the patient's chest, and connects them to the Holter monitor. They provide instructions on how to keep a diary of activities and symptoms throughout the monitoring period.
Next, the assistant reviews the recorded data, making note of any abnormalities or irregularities. They may ask the patient to wear the monitor for 24 to 48 hours or longer, depending on the doctor's instructions, to gather a comprehensive assessment of the patient's cardiac activity.
