Holter Monitor

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)
  • dizziness
  • 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.
