HOLTER STUDIES
Why did my doctor order a Holter Monitor test for me?
The Holter monitor will assist your doctor in determining whether the symptoms you are experiencing are related to your heart. If a problem with your heart is detected, the Holter monitor will assist your doctor in determining the nature and severity of the problem.
Will there be any pain involved with the Holter test?
The Holter monitor test is quite painless. The only discomfort you may experience is when removing the electrode patches (similar to removing a Band-Aid). Also, a small number of people are allergic to the patches and may develop a minor skin rash, which will usually go away within a few days after the patches are removed.
How long must I wear the monitor?
The Holter monitor must be worn at all times during the test period which typically ranges from 24 to 48 hours, depending on how long your doctor feels you need to be monitored.
What if a patch comes off?
Simply press it back on in the same location. If a lead wire comes off the patch, snap it back on. Always mark these events in the diary along with the time that they occurred.
How will I be billed?
We will directly bill your primary and secondary insurance carrier, whether you have Medicare Part B, private insurance or belong to any HMO. You, of course, will be billed for any co-pays or deductibles, if any.
How do I return the Holter Monitor?
If it was placed at the physician's office or a hospital, it should be returned there unless you were instructed otherwise. If the monitor was shipped to you, it should be returned in the pre paid shipping bag that was provided.

CARDIAC EVENT MONITOR
Why did my doctor order a Cardiac Event Monitor test for me?
The cardiac event monitor will assist your doctor in determining whether the symptoms you are experiencing are related to your heart. If a problem with your heart is detected, the cardiac event monitor will assist your doctor in determining the nature and severity of the problem.
I've already worn a Holter monitor. Why did my physician order an event monitor?
- The Holter monitor only captures 1-2 days of your life when you may not be having symptoms.
- Further evaluate the symptoms from the Holter monitor
- Regulate a change in medication to document changes in your heart pattern
- Follow up to a procedure to document changes in your heart pattern
Will there be any pain involved with the test?
No, the only pain you may receive is during the removal of electrodes, which is similar to removing a band aid.
How often must I wear the monitor?
The cardiac event monitor must be worn at all times during the test period which may range from one to four weeks, depending on how long your doctor feels you need to be monitored. The monitor and cable must be removed prior to bathing or showering. The electrodes can remain on your skin as long as they appear to be firmly attached.
Can I wear the Cardiac Event Monitor on an airplane?
Yes, but you should inquire with the airline about security procedures that may apply.
How will I be billed?
We will directly bill your primary and secondary insurance carrier, whether you have Medicare Part B, private insurance or belong to any HMO. You, of course, will be billed for any co-pays or deductibles, if any.
