What is a millitesla examination?

Generally, a Holter monitor test refers to a 24-hour ambulatory electrocardiography (ECG) monitoring, which serves as a supplementary method to standard ECG testing. The specific details are as follows:

A 24-hour ambulatory ECG monitoring is a non-invasive diagnostic procedure used to evaluate the heart's electrical activity. This test employs a portable ECG recording device that the patient wears on their body while carrying out normal daily activities over a 24-hour period. The recording device is connected to multiple electrodes placed on the patient’s chest, continuously capturing and storing data on the heart's electrical activity. By recording and analyzing the patient’s ECG patterns throughout the 24 hours, it helps detect variations and abnormalities in cardiac electrical activity during routine daily life. It is commonly used to assess arrhythmias, sinoatrial node dysfunction, angina pectoris, and myocardial ischemia.

Prior to undergoing a 24-hour ambulatory ECG monitoring, patients need to follow the doctor’s instructions for proper preparation, such as avoiding contact with water, oils, or organic solvents, to prevent interference with the test results.
