Holter/Event Monitoring

Holter/Event Monitoring


What is a Holter monitor?

A Holter monitor is a small, wearable device that records your heart rhythm continuously for up to 72 hours.

What is an event monitor?

An event monitor is a wearable device that records your heart continuously for 3-30 days. The recordings are monitored  throughout the day by support staff at the company that supplies the monitor, and urgent findings are reported to your doctor. Your doctor can see what your heart rhythm is doing during your normal activities and learn of abnormal rhythms that may be concerning, but not causing you symptoms. If you do experience symptoms, you will be asked to push buttons on the monitor to indicate the time and type of symptom.

Why is your doctor ordering monitoring?

Holter and event monitoring can help your doctor:

  • Study symptoms like palpitations, shortness of breath, dizziness, or fainting that may be heart related.
  • Identify irregular heartbeats.
  • Check how well an implanted pacemaker is working.
  • Check how well your medications are working.

Holter monitoring: what to expect

A technician will place electrodes, or patches, on your chest. The monitor will be connected to the patches with wires, and then clipped to your belt or pocket or worn around your neck. After you get instructions, you can return to your usual activities, unless your doctor tells you otherwise. You will be asked to keep a diary of symptoms you notice while wearing the monitor.

Event monitoring: what to expect

Typically the monitor is mailed to you with instructions on how to place the electrodes and operate the monitor. You will wear two electrodes on your chest that will be connected to the monitor throughout the day, except when bathing. You will return the monitor in postage-paid envelope.
