If you suffer from palpitations (fast, strong, or irregular heartbeats), fainting and dizziness spells, your doctor may recommend Holter monitoring to be able to correlate these symptoms to your heart rhythm. This test allows transient (temporary) rhythm disorders of the heart to be detected.
Your cardiologist may recommend Holter monitoring to study the electrical activity of your heart under normal activity or after a heart attack. It 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 after a heart procedure to see if the procedure was successful.
