If you suffer from palpitations (fast, strong or irregular heartbeats),or fainting and dizziness spells, your doctor may suggest Holter monitoring to compare these symptoms to your heart rhythm. This test allows transient (short term) rhythm disorders of the heart to be detected.
Your cardiologist may advise Holter monitoring to assess the electrical activity of your heart under normal activity or following a heart attack. Holter monitoring also allows the cardiologist to diagnose any heart rhythm abnormalities (including serious arrhythmias) and to monitor the effect of a new heart medicine. It is also useful for monitoring your heart rhythm following a heart procedure to determine if the procedure was successful.
