Event Recording: To Transmit or Save Events
Step 3: Start Recording
1.
The recording will begin automatically after
15 seconds. At first you may see the ECG
signal and quality on the screen. The quality
can range anywhere between 0 (no signal)
to 5 (best signal). A rating of 3 or above
should suffice, although you may want to
get a signal of 5 before continuing. To view
the ECG again, just remove the cable and
re-insert. There will be a 10-second delay.
2.
During recording, time-of-day appears on
the screen. Once recording begins, it will
continue to record until the battery is
removed or the memory is full.
3.
The patient can choose between a belt clip
or pouch with strap for wearing the
recorder. All equipment, except the elec-
trodes and a portion of the lead wires,
should be over at least one layer of clothing
so that it is not in direct contact with the
patient’s skin. Orient the recorder on the
patient so that the EVENT button is acces-
sible and the LCD is visible.
4.
Advise the patient to not expose the
recorder or electrodes to any wet environ-
ment; in addition, they should not shower,
bathe, or swim while wearing the recorder.
5.
Instruct the patient how to use the EVENT
button to record symptomatic events.
Advise them to push the EVENT button
briefly; when they use it depends on your
institution’s procedures.
Note: Although the recorder’s false negative
rate is low, there is always the potential that
an arrhythmic event being experienced by a
patient is not captured automatically by the
recorder. Therefore, we strongly recommend
that even when automatic detection is turned
on, that patients be informed that they should
always press the EVENT button when they
feel they are having an arrhythmic event.
6.
If you choose, instruct the patient when and
how to send the recordings via the tele-
phone.
7.
When the patient returns, review the screen
first to ensure that all events have been sent.
8.
If the screen states that there are “Events
Recorded” and does not state that any were
“sent”, you will now need to transmit and
save the events for the patient.
To stop recording
After transmitting and erasing any unsent
events, remove the electrodes, leads and
recorder from the patient. You should now
open the recorder and remove the battery to
stop operation.
To Transmit or Save Events
At the beginning of the transmission a cal sig-
nal will be present. Additionally, at the begin-
ning of each event there will be a marker. The
marker is a digital signal that will include the
serial number of the recorder and the time, date
and type of each event. The digital signal can
only be read by the NorthEast Monitoring LX
Event software. If you are using a different
event recorder software, you will not be able to
read the digital signal, but the signal will allow
you to tell where each event begins.
There are a few ways to obtain the event data
that has been saved on your recorder:
1. Acoustic Transmission
Start the software application or recording
device that will be recording the events. Once
recording has begun, press the ENTER button
on the recorder for a second and the events will
begin transmitting. Transmission will continue
until all events are sent. Once the events are
sent, you can now erase them from the recorder
by pressing either one of the green arrows for 3
seconds.
The recorder’s ECG transmission uses the stan-
dard FM transmission. The header uses a pro-
prietary format.
