Named for Norman J. Holter, a pioneer in cardiac telemetry, a Holter Monitor is a portable device that monitors your heart's activity as you go about your daily routine.
The purpose of this test is to determine the presence and severity of disturbances in your heart rhythm. The monitor can detect heart rhythm disturbances you may be having, such as dizziness, palpitations, or fainting spells. The test involves placing ECG wires attached to a box, similar to a small tape recorder, on your chest. You will wear this for 24 to 48 hours. You will be asked to keep a diary and record any symptoms you have, and what you were doing when they occurred. The test will then be analyzed, and symptoms will be correlated with any disturbances in your heart rhythm.
