Wireless Cardiac Monitor Uses Cellular Phone Technology

Posted on An advanced wireless device integrates cardiac arrhythmiamonitoring and cell phone technologies in one unit.

The ER920W Wireless Cardiac Arrhythmia Monitor is a digital looprecorder with on-board arrhythmia detection algorithms forautomatic detection, recording, and immediate transmission ofpatient data files to a round-the-clock monitoring service centerfor analysis and physician attention. Transmission occurs withoutpatient interaction and without connection through a separate cellphone, reducing potential anomalies in the prescribed testingroutine and avoiding the possibility of the patient forgetting tocarry the cell phone. The ER920W enhances diagnostic yield withembedded algorithms that automatically detect, record andimmediately transmit asymptomatic events such as atrialfibrillation, bradycardia, tachycardia, and cardiac pause.

The monitor's telecommunications architecture, including cellularnetwork, Internet, and the proprietary management softwareinterface, allows for bidirectional data flow, so the physician canmonitor the patient's cardiac events and remotely program thedevice as required. The cellular transmitter embedded in the ER920Wuses a quad-band modem for maximum flexibility and is compatiblewith both Global System for Mobile (GSM) and General Packet RadioService (GPRS) cellular networks. The ER920W Wireless CardiacArrhythmia Monitor is manufactured by Braemar (Minneapolis, MN,USA), a subsidiary of Biotel (Eagan, MN, USA), and has beenapproved by the U.S. Food and Drug Administration (FDA).

The ER920W is an advanced arrhythmia monitor with proprietarytechnology that we believe represents the next generation ofcardiac event monitoring, said Harry Strandquist, president ofBraemar. The ER920W provides faster patient diagnosis, improvespatient compliance, and is far superior to the current cumbersometransmission method. This device is the first in a series ofBraemar wireless arrhythmia monitoring products currently underdevelopment.

Cardiac arrhythmia monitors are worn by patients for up to 30 daysto document and record transient cardiac events. Recording ofsymptomatic events such as syncope, palpitations, dizziness, chestdiscomfort, and shortness of breath is activated by the patient.
