VIVAQUANT, INC. RX-1 Rhythm Express

The Rhythm Express RX-1 will be worn by adult patients for a period of time as prescribed by a physician, typically 1 day to 4 weeks, and will continuously monitor ECG. RX-1 will function in one of three modes: a) Mobile Cardiac Telemetry (MCT), b) Event Recorder (ER), and Wireless Holter (WH). The device will connect to standard ECG electrodes to capture 2 channel ECGs. An embedded algorithm processes the acquired ECG to detect arrhythmias, compress the ECG, and remove most in-band noise without distorting ECG morphology. RX-1 incorporates a cellular modem to communicate with the RS-1 Web Service. The RX-1 device uses an embedded cellular modem on the Verizon LTE network.The RX-1 device is not a life-supporting or life-sustaining system. Clinical judgment and experience are used to check and interpret the data.
