This page answers the following questions frequently asked by patients about our services. 


Q: What is a Holter monitor?

          A Holter monitor is a small, lightweight, diagnostic recording device.  It is used to record your electrocardiogram (ECG) while you are normally active.  It is able to record two or three channels (views) of your ECG continuously for 24, 48 or 72-hours.  Holter monitoring is a form of ambulatory cardiac monitoring.

          Holter monitors have an event button that can be activated when you experience a cardiac symptom.  When the event button is pushed, an indicator mark is placed on the recording so we can see on your ECG where you experienced the symptom.  During the time you wear the monitor, you will maintain a diary of your symptoms and activities.  Your doctor will be able to match these symptoms and activities with your ECG rhythms.

        The Holter monitor continuously measures from your skin surface, via the electrodes, electrical activity generated by your heart muscle and stores it permanently on magnetic tape or onto a memory flashcard.  The monitor is  connected to your chest using 5-7 adhesive electrodes.  Electrodes conduct electrical activity from the skin surface to the electrode wires.  Lead-wires snap onto the electrodes and are attached to the monitor at the other end by a connector.  The current moves from the skin surface through the electrodes and up the lead-wires directly into the recorder.  

          This device was invented by Jeff Holter, PhD., from Missoula, Montana.  Originally, it was a large pack of equipment that was worn on the patient's back.  Of course, since that time, these devices have been miniaturized.  


Q: What is a cardiac event monitor?

          A cardiac event monitor is smaller and lighter than the Holter.  It is also a diagnostic recording device.  Like the Holter monitor, it is used to record the electrocardiogram (ECG) while you are normally active.  It records one channel (view) of your ECG for up to 30 days (usually about 2 weeks).  However, it does not record continuously.  It records only when you activate it during symptomatic episodes.  Depending upon how the monitor is programmed, it will hold 2-3 event recordings.  When the monitor is full, you will be alerted to transmit the recordings by telephone back to CardioGraphics.  Cardiac event monitoring is also a form of ambulatory cardiac monitoring.

          Cardiac event monitors have an event button that can be activated when you experience a cardiac symptom.  When the event button is pushed, the monitor records.  It is able, by the use of "looping" memory, to record both before and after the button is pushed.  During the time you wear the monitor, you will maintain a diary of your symptoms and activities.  You will relay the symptoms and activities you experienced with each recording to CardioGraphics' nurse or cardiovascular technologist at the time you transmit the recordings.

        The cardiac event monitor continuously measures from your skin surface, via the electrodes, electrical activity generated by your heart muscle.  It stores a sample of your ECG onto non-volatile internal memory when you activate the recorder by pushing the Record button.  The monitor is  connected to your chest using 2 adhesive electrodes.  Lead-wires snap onto the electrodes and are attached to the monitor at the other end by a connector. The ECG data remains in the monitor's memory until it is transmitted by telephone back to CardioGraphics. 

Q: Why should I wear a heart monitor?

          Your doctor has ordered a Holter or cardiac event monitor for you because you told him of a symptom, or symptoms, that indicate your heart may have an abnormal rhythm.  These studies will either confirm the arrhythmia, rule it out as the source of your symptom(s) or indicate that additional tests need to be performed.


Q: Where do I go to get my heart monitoring equipment?

          CardioGraphics can provide you with a cardiac monitor at a scheduled time or on a drop-in basis, right in our office.  If you are unable to come to our office, we may be able to arrange to meet you at your ordering physician's office.

Q: What if I live outside the Portland/Metropolitan Area?

          
If you live outside the Portland/Metropolitan area and your doctor has ordered a monitor, we can mail it directly to you.  Included with the monitor are detailed instructions, a hook-up kit and a prepaid mailer that can be used to conveniently return the monitor once the study is complete.

Q: Can I take a bath or shower when I'm wearing this monitor?

         
When wearing a Holter monitor, most daily activities are unaffected.  You may not, however, take a bath or shower during the course of the study.  When wearing a cardiac event monitor, you may take a bath or shower, but you must remember to leave the monitor outside the bathroom  Both water and steam will damage these monitors!

Q: How long will the appointment last?

        
It takes about 15 minutes for us to connect you to a Holter monitor and provide you with instructions.  We require approximately 20-30 minutes to connect you to a cardiac event monitor.

Q: Does my insurance cover this service?

         
Most insurance companies cover the cardiac services that we provide.  The level of coverage solely depends on your policy.  Please remember, if you have a co-pay or deductible, it is due at the time of service.  If you have any questions regarding your coverage, please contact our Business Office.

Q: How long do I have to wear the monitor?

         
Holter monitors are worn for 24,  48 or 72-hour periods.  Cardiac event monitors are typically worn until your symptoms are documented (usually two weeks or less) up to a maximum of 30 days.

Q: How long does it take to get my results?

         
The results of studies performed by CardioGraphics are transmitted electronically to large hospital accounts, or are delivered by courier or US mail to your physician or hospital.  Holter studies are completed by priority.  The results are usually sent to your doctor within two business days following the date we receive your recording.  Cardiac event study results are usually sent the next business day following the date the recording is transmitted to us.  If your doctor requests a cardiologist interpretation, your doctor will not receive a final report until several business days after the interpretation is completed. 

Q: What if I run out of electrodes?

           
If you are using one of our monitors and you need additional electrodes, please call us at 971 236-9175 or 800 574-1395.

Q: What if my electrodes fall off and/or my wires become disconnected?

           
If you have a Holter monitor and your wires become disconnected or your electrodes fall off, reconnect or apply them to their original positions as soon as possible.  Please click here to see a diagram of the placement of your electrodes.  If you are wearing an event monitor and this occurs, reapply new electrodes and attach the wires to their previous positions.  If you have any questions regarding the placements of the wires and/or electrodes, give us a call.  

If your question was not answered here, please call us at 971 236-9175 or 800 574-1395.
