what is a holter monitor

A Holter monitor is a type of ambulatory electrocardiography device used for cardiac monitoring for at least 24 hours. It is a portable device that records the heart's rhythm and is most commonly used to monitor ECG heart activity, especially for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period. The monitor uses electrodes and a recording device to track the heart's rhythm, and the recorded data can be used to detect or determine the risk of irregular heartbeats. It is typically recommended for individuals who have signs and symptoms of an irregular heart rhythm, unexplained fainting, or a heart condition that increases the risk of arrhythmias. The monitor is placed at a healthcare provider's office during a scheduled appointment, and the recorded data is analyzed by a healthcare professional to determine an appropriate treatment plan if necessary
