Chapter 1 -About the DR400
The NorthEast Monitoring DR400 patch style recorder can be used as either a Holter mon-
itor and/or a looping Event recorder. Data obtained by monitoring is not analyzed at the
time of recording. After recording is complete, Holter data is uploaded to a compatible ver-
sion of NorthEast Monitoring’s Holter Analysis software. The DR400 recorder is compati-
ble with 5.2 or newer versions of HE/LX Analysis software. For Event, data is sent
wirelessly to a location where versions 2.11 or newer of the LX Event utility is used to
review and report on the recording.
The DR400 Recorder is not intended to replace real-time telemetry monitoring for
patients suspected of having life-threatening arrhythmias.
The DR400 Recorder is not for In Vitro diagnostic use.
