Frequently Asked Questions

Why has your doctor asked you to wear this monitor?

Your doctor wants to gain a deeper understanding of your heart rhythm to provide you with the best possible care. The RX-1 mini continuously records your heart’s electrical activity while you are wearing it, capturing even brief, transient events which might last only a few seconds. By wearing the monitor as much as possible, you’re providing your doctor with comprehensive, actionable data to guide your treatment effectively.

The RX-1 mini is an advanced cardiac monitoring solution that constantly checks for any abnormal heart rhythms. It securely transmits data to our monitoring center using a built-in cellular communications chip. Depending on your doctor’s configuration, our team of expert U.S.-based clinicians in Dallas, Texas, reviews the information 24/7/365 and provides a detailed report to your doctor. Your role is simply to wear the monitor and go about your daily activities!

Open and read the Quickstart guide. We’re here to ensure you have a smooth start to your monitoring journey. You can also call our dedicated support line at 866-324-8783 and press option #1 for personalized assistance with device setup and placement. Our experienced team will guide you through the process, ensuring your comfort and the device’s optimal functionality.

Your Rhythm Express kit includes:

  • RX-1 mini device: Our state-of-the-art monitor that collects and transmits your heart rhythm data
  • Charger: Used to charge the battery throughout your monitoring period, like other rechargeable devices you may have at home.
  • ECG electrodes: High-quality sensors that detect your heart’s electrical signals and connect to the RX-1 mini leads

For the most comprehensive monitoring, we recommend wearing the RX-1 mini continuously, including while you sleep. The device is designed for comfort and convenience, allowing you to wear it during most daily activities, even in the shower, thanks to its water-resistant design.

Absolutely! The RX-1 mini is designed to accompany you wherever you go. Its compact size and built-in cellular technology mean you can travel freely without interrupting your monitoring. Just remember to bring your charger for longer trips. If you are traveling outside of the United States, your device will continue to collect data, but your physician won’t get data about your heart rhythm until you return. Also, bring your charger on these trips, and remember to bring an appropriate power adaptor for the country to which you are traveling.

*Please note, If your physician has prescribed a Holter monitor, the data collected is not reviewed and reported upon until the test is complete. 

No additional internet or cellular plan is required. The RX-1 mini comes equipped with its own cellular chip, ensuring secure data transmission regardless of your location or personal cellular plan.

The RX-1 mini can last up to 5 days on a single charge. We recommend charging your device at least every 3 days to ensure uninterrupted monitoring. The battery indicator will blink amber when it’s time to charge. This can typically be done while you’re stationary, such as when watching TV or reading.

Caution: Never charge the device while wearing.

A full charge usually takes about 1.5 hours when the battery is completely discharged.

It’s normal for the device to warm slightly during charging. If it feels uncomfortably warm when charging is complete, allow it to cool before reapplying. If you have any concerns, don’t hesitate to contact our 24/7/365 support line.

Once your prescribed monitoring period is complete, please return the RX-1 mini promptly using the provided shipping label. This ensures that your doctor receives your full monitoring report as quickly as possible, allowing for timely analysis and any necessary adjustments to your care plan.

Remember, our support team is available 24/7/365 at 866-324-8783 or via email at [email protected] for any questions or assistance you may need during your monitoring period. Your heart health journey is our priority, and we’re here to support you every step of the way.
