Q: What kind of information does PocketECG provide my doctor?

A: PocketECG provides your doctor with complete information about your cardiac rhythms and your heart rate to help in the diagnosis of cardiac arrhythmia.

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

A: Your physician will decide the length of your cardiac study. PocketECG can monitor your cardiac rhythms for up to 30 days to provide the data needed for a more accurate diagnosis.

Q: Will the monitor prevent me from having a stroke or a heart attack?

A: No. PocketECG is a diagnostic tool used to help detect cardiac arrhythmia. It cannot prevent a stroke or a heart attack.

Q: Will you call EMS if I have a life-threatening arrhythmia?

A: No. MediLynx provides diagnostic cardiac rhythm analysis, but we do not provide emergency monitoring services. The results of your monitoring study are reported to your treating physician, or other healthcare provider, at the conclusion of your study. We also notify your healthcare provider of certain emergent rhythm data based on criteria set by your provider. If you believe you are having a medical emergency, please call 911.

Q: Do I wear a monitor all the time, even when I sleep?

A: The monitor should always be worn, except when showering, bathing, or swimming, unless otherwise instructed by your physician.


Q: Do I need an Internet connection for the monitor to work at home?

A: No. PocketECG transmits your ECG data directly from the device to MediLynx using a mobile network.

Q: What if I live in an area with poor or no cell service?

A: Don’t worry if you don’t have cell service or your cell service is poor. Your heart rhythm data is constantly recorded and stored in the device’s internal memory. If the cellular connection is interrupted, the device will continue to record your data and will transmit all the data once the connection is restored. If no cellular connection is available for the duration of your study, your data will be downloaded when you return your device to MediLynx.

Q: How do I know if the monitor is properly connected and transmitting data?

A: If no ECG data is transmitted for more than six consecutive hours, a Customer Care team member will contact you to troubleshoot the problem so that your study continues as quickly as possible. You can also request a data check by calling the ECG Center at 1-855-847-1009 to ensure that your device is connected properly and transmitting data.


Q: My PocketECG kit includes two types of electrodes, which set should I use?

A: Your PocketECG device comes with two types of latex-free, hypoallergenic electrodes for your convenience. Most patients start out with the Vermed® foam electrodes in the silver packaging, as they adhere to the skin more easily.  However, if you experience skin sensitivity or irritation, you may try the alternate electrodes.  Feel free to contact Customer Care at 1-855-847-1009 for more information about electrodes.

Q: Do I need to replace my electrodes? If so, how often and when?

A: Yes. You should replace your electrodes every 24 hours to ensure clear, readable data. Most people prefer to change their electrodes when they bathe, but you can change them whenever it is most convenient. Your PocketECG comes with a 30-day supply of each type of electrodes, and additional electrodes can be provided if needed.

Q: How do I replace my electrodes?

A: To change your electrodes, unsnap the leads from the electrodes and remove the device, leaving the electrodes on the skin. Using warm, soapy water, loosen the adhesive and detach the electrodes. Be sure not to get the PocketECG device wet. To reattach, wait until the area is completely dry and free of any barriers between the skin and the electrode (hair, lotion, ointments, etc.). Replace the electrode within 3 inches of the original placement.

Q: What should I do with my spare battery when it is not in use?

A: You should always leave the spare battery on the charger when not in use, so that it is fully charged when needed.

Q: Why did my screen turn off when I was reporting a symptom?

A: The screen will turn off to conserve battery power if too much time passes while you are selecting from the symptoms on the screen. The device will also turn off if the PocketECG button is held down for too long. If you need help reporting symptoms, call our ECG Center at 1-855-847-1009 and a technician will assist you.

Q: What does it mean when my device reads ``Report Symptoms`` even if I don’t have any symptoms?

A: The Report Symptoms screen acts as a “home screen” on the device, so that if you do have any cardiac symptoms, you can easily tap on it and follow the prompts to report the symptoms.


Q: Is there someone that I can call with questions while I am wearing the monitor?

A: Yes, please call us at 1-855-847-1009 and one of our Customer Care Representatives will be happy to answer any questions you may have.

Q: If the device detects an unusual rhythm, will my doctor be notified?

A: If an unusual rhythm is detected according to criteria set by your doctor, your doctor will be notified and provided with a report.

Q: Should I call the Customer Care Center when I bathe or swim?

A: There’s no need to call Customer Care when you bathe or swim, but always be sure to remove the device prior to showering, bathing, or swimming. If you remove the device for more than six consecutive hours, a Customer Care team member may contact you.

Q: Once my session is complete, may I obtain a copy of my report?

A: Yes, you may contact your physician for a copy of your report. Alternatively, MediLynx can provide you with a copy of your report if you complete and sign a medical release form. Please contact Customer Care for more information.

Q: How do I get information on my cardiac rhythm and heart rate?

A: MediLynx provides your physician with a diagnostic report, who then interprets the report to guide your treatment. Please contact your physician for any questions regarding your cardiac rhythm or your heart rate.   However, as noted above, you can request a copy of your report from your physician, or from MediLynx if you complete and sign a medical release form.
