What is the purpose of Holter monitoring?

Holter monitoring serves the purpose of continuously recording the heart's electrical activity over an extended period, typically 24 to 48 hours. This non-invasive procedure allows healthcare providers to assess the heart's rhythm and detect any abnormal electrical activity that may not appear during a standard electrocardiogram (ECG) performed in a clinical setting. By using a portable device that the patient wears, physicians can correlate the results with the patient's symptoms and activities throughout the day, leading to a comprehensive understanding of their cardiac health.

The other options don't align with the function of Holter monitoring: measuring blood pressure pertains to a different type of monitoring, assessing lung function is related to pulmonary tests, and detecting cholesterol levels involves blood tests rather than continuous heart activity recording. Each of these processes focuses on a different aspect of health that does not involve the continuous electrical assessment of the heart.
