Chapter 1 -Introduction
The NorthEast Monitoring DR200/HE and DR300 Digital Recorders can be used as either a Holter monitor or a loop-
ing Event recorder. The DR200/HE and DR300 Digital Recorders are designed to facilitate ambulatory cardiac moni-
toring, on order of a physician, of those patients (including infants weighing less than 10 kg.) who may benefit from
such monitoring, including but not limited to those with complaints of palpitations, syncope, chest pains, shortness of
breath, or those who need to be monitored to judge their current cardiac function, such as patients who have recently
received pacemakers.
The data obtained by monitoring is not analyzed at the time of recording. After the recording
is complete, the data must be downloaded to a compatible version of NorthEast Monitoring,
Holter LX Analysis or LX Event software to be analyzed.
The DR200/HE and DR300 Digital Recorders are compatible with 5.2 or newer versions of
Holter LX Analysis. The DR300 Digital Recorder in wireless mode for event recording, is
compatible with LX Event version 2.11 or newer.
