Holter and Event Loop Monitoring
Make Appointments & Get Care
What is Holter and Event Loop Monitoring?
Holter, MCOT, and event monitors are wearable devices used to detect heart rhythm problems such as the cause of palpitations, and heart beats that are too fast, too slow, or irregular. They include a diary where you can note symptoms while wearing the monitor. This can help your doctor assess if your heart rhythm is associated with your symptoms.
UR Medicine's Approach
Holter, MCOT, and event monitors are wearable devices used to detect heart rhythm problems such as the cause of palpitations, and heart beats that are too fast, too slow, or irregular. They include a diary where you can note symptoms while wearing the monitor. This can help your doctor assess if your heart rhythm is associated with your symptoms.
At UR Medicine, we offer the following monitors:
Holter monitors are portable devices that track your heart rhythm activity anywhere from 1-2 days, or 1-2 weeks at a time. The recorded information is sent back to your doctor for analysis.
- Modern holter monitors are in a wireless patch that’s worn on the chest.
- Traditional holter monitors have wires attached to several electrodes on the chest and abdomen.
Mobile Continuous Outpatient Telemetry (MCOT) and Event Monitors are portable devices that record a beat-by-beat analysis of your heart’s activity, worn for up to 30 days. If the MCOT device detects an abnormality in your heart rate, it will send a report to your doctor. In addition to more urgent information, a final analysis will be provided at the end of the monitoring period.
What to Expect
- A technician will place several electrodes and wires on your chest and abdomen which connect to the monitor.
- The monitor can be clipped to your waistband or worn like a necklace.
- At the end of the testing period, usually one to two days, you will return the monitor so the data can be analyzed.
- A technician will attach a patch to your chest that has a wireless sensor clipped into it. We also offer the option of mailing a kit to your home that includes instructions to place the monitor yourself.
- Information is recorded by the sensor for the duration of time the monitor is ordered for – typically 2 days, 1 week, or 2 weeks.
- You will be provided with a diary to write down the date and time you experience any symptoms while wearing the monitor.
- At the end of the monitoring period, you will return or ship back the sensor and diary so the data can be analyzed.
- A technician will attach a patch to your chest that has a wireless sensor clipped into it. You will also be provided with a smartphone that’s used to transmit data and record any symptomatic events you might experience while wearing the monitor.
- When you feel symptoms such as palpitations, you should use the smartphone to record the event and note your symptoms.
- Information on your heart rhythm is then stored, or in some cases, transmitted for immediate analysis by your doctor.
At the end of the testing period – typically one to four weeks – you will return the monitor so the data can be analyzed and put into a final report.
When symptoms are infrequent or hard to detect with wearable monitoring options, some patients may be eligible to receive an implantable cardiac monitor (ICM).
- ICM’s are small devices, about the size of a jumbo paper clip or pen cap, that are implanted under the skin in the mid chest area. The procedure with local numbing medication. It is a quick procedure that does not result in any down time.
- ICM’s continuously look for abnormal heart rhythms within a range of predetermined settings that are unique to each patient’s needs.
- An ICM battery can last from 3 to 7 years based on the model. It’s monitored remotely from home every 30 days with a bedside monitor or app installed on your phone. The data collected each month is reviewed by your provider.
ICM’s also come with an activator that can be used by the patient to record your heart rhythm during times you are experiencing symptoms. These events can then be transmitted to your provider.
Frequently Asked Questions
- For traditional Holter monitors and patch-style monitors, analysis of the information recorded begins after the monitor is returned. Once the monitor is returned, it takes about one to two weeks for the results to become available.
- For MCOT and event monitors, same day analysis of abnormal heart rhythms are reported while you are wearing the monitor (if in an area with cell service). All other data is analyzed and put into a final report that is available for review about one to two weeks after mailing back the monitor.
- Patch style monitors are water resistant and can be worn in the shower, however, they are not waterproof, so submerging them in water (such as in the tub or while swimming) is discouraged.
- Traditional Holter monitors with wires are NOT water resistant and should be taken off during bathing or while swimming.
Possibly. Hypoallergenic patches are available for those that have known skin sensitivities. Many of our heart monitoring options also come with a set of wires to use in place of the patch for those that cannot tolerate wearing the patch. If you have a known sensitivity to adhesives, please discuss it with your doctor ahead of time so you can decide what is the best monitoring option.
- MCOT and event monitor sensors need to be charged about every 5 days, and the smartphone that transmits data needs to be charged daily. Instructions, extra patches, and charging cords are included with the kit that is provided to you.
- Patch-style Holter monitors do not require any charging.
Yes. Ideally, the smartphone should always be within 5-10 feet of you while wearing the monitor so there is no delay in automatic transmissions being sent to your doctor in the event the device detects a concerning heart rhythm. Reliable cell service in your location is required for this type of monitor to transmit data.
No. The smartphone that is provided with these monitors cannot make calls, text, access the internet, or download any apps. It is strictly used to transmit and record your heart rhythm data as well as store any symptoms you might experience.
