Instructions for Use

If your doctor provided you with the RX-1 mini to monitor your heart, congratulations! Your doctor has chosen the best, the Rhythm Express RX-1 mini.

Why has your doctor asked you to wear this monitor?

Your doctor wants to better understand your heart rhythm to better guide your care. The RX-1 mini you will wear continuously records the electrical activity of your heart. The heart activity your doctor is looking for is often short lived, sometimes lasting only a few seconds. It’s therefore important that you wear the monitor as much as possible, so your doctor receives the best information.

How does the device work?

The RX-1 mini checks for any abnormal heart rhythms. Data are securely transmitted to our monitoring center using a cellular communications chip located inside the device. Depending on how your doctor configured the RX-1 mini, our team of technicians in Dallas, Texas reviews the information 24/7/365 and provides a report to your doctor. All you need to do is wear the monitor!
