Holter Monitor

A Holter Monitor is a diagnostic test used to evaluate your heart rate and rhythm while you go about your normal daily activities.

Usually there are no special preparations for a Holter Monitor test.

What to expect during a Holter Monitor test

  • A nurse or technician will explain the entire procedure to you prior to the test. Do not hesitate to ask any questions you may have at this time.
  • Several adhesive patches, called electrodes, will be placed on your chest. These will be connected to a tape-recording monitor so that your heart rate and rhythm can be continuously recorded during the next 24 hours.
  • The monitor, called a Holter Monitor, will remain attached to you for the next 24 hours. Either a shoulder strap or a belt will be provided so you can carry the monitor conveniently. The Holter Monitor weighs approximately 1 pound.
  • While you are wearing the Holter Monitor, you will be asked to keep a diary of your activities and symptoms (i.e., palpitations, shortness of breath, chest pains, etc.).
  • You will then be asked to return the next day (approximately the same time), and the Holter Monitor will be removed. Your diary will be reviewed by the nurse or technician to be sure they understand you entries. You will then be allowed to leave.
  • Your Holter Monitor data will be scanned on a computer and reviewed and interpreted by a cardiologist. The cardiologist will submit a full written report to your personal physician. Your personal physician will then explain the results of the test and their implications to you.
