You may have a Holter Monitor test if you experience:
- palpitations (an unpleasant sensation in the chest due to an irregular or forceful beating of the heart)
- shortness of breath
- chest pain
Holter monitoring diagnoses irregular heart rhythms.
- During this test, electrodes are placed on the chest and connected to a small device that records heart rate and rhythm.
- Typically, people wear this device for a 24-hour period while performing regular daily activities.
