The price of a 24-hour ambulatory electrocardiogram is usually $200-300, with slight variations in charges in different areas and hospitals. 24-hour ambulatory electrocardiogram, also known as Holter monitoring, is a test that can continuously record changes in a patient’s electrocardiogram over a 24-hour period. Conventional ECG monitoring is short, only a few seconds, and the chance of detecting disease is not high, while 24-hour ambulatory ECG monitoring is long and the chance of detecting disease is higher. The 24-hour ECG is mainly important for the diagnosis of myocardial ischemia and arrhythmia. On the day of the test, you need to stay away from places with magnetic fields, and you cannot use magnetic items such as electromagnetic stoves, electric mattresses, electromagnetic beds, etc. You cannot have CT or MRI tests. If you need to have a 24-hour dynamic electrocardiogram, please go to a regular hospital. This kind of examination is very helpful in analyzing the results and detecting diseases.
