Chapter 2 -Recording ECG
Below are the steps to complete a procedure using the DR400:
Step 1: Fully charge the DR400
You must fully charge your recorder before its first and every use.
To charge the internal lithium battery,
place the battery into the docking station, and with the USB cable attached, plug the cable into the power
adapter. When plugged in, the DR400 will flash orange while charging, and once fully charged, will flash
green every 5 seconds. At this point, you can remove the DR400 from the docking station, and the recorder
will stop flashing and go into standby mode.
It takes approximately 2 hours to fully charge the battery from having no charge. A fully charged battery will
record Holter for up to 14 days, but we highly recommend that you charge the DR400 between patients. For
24 hour recordings, this will take only about 10 minutes between recordings. For long Event recordings, the
DR400 should be charged every 14 days.
If the DR400 is used frequently, for example, not left in the charger for more than a day or two, it is fine to
keep it plugged in between uses. If you use your DR400 less frequently, for example it might be plugged in
for more than a few days, it is best to remove the DR400 from the charger once full charged. You will then
want to plug it in again to ensure it is fully charged before your next study, but that should only take a few
minutes.
Step 2: Start the PCPatch utility
See chapter 3, The PCPatch Utility, for more information on using the PC Patch.
Place the fully charged DR400 into the docking station and attach the docking station to the
PC using the USB cable. Start the PCPatch utility and:
1.
ERASE any data on the DR400. This will also update date and time.
2.
Enter a New Patient ID for the next recording.
3.
For DR400 v5.22 and greater, you can now click on the Start DR400 button in the PCPatch window. If
started, you will see a message that the DR400 will start once removed from the docking station.
If you see a message “THIS DR400 CANNOT BE STARTED VIA THIS BUTTON...,” you will need to
start the recorder as described in Step 4: Hook up Patient.
Step 3: Prepare patient
Patient preparation and patch placement is critical to obtain a quality ECG signal. To ensure proper hook-up,
follow these steps:
1.
There are four hook-up options for the DR400:
Select either a 1-lead electrode patch (1CH) for event or Holter, a 1-lead electrode with the addition of a
ECG lead wire (3CH), a 3-lead patch (3CH) or the reusable 3-lead adapter.
2.
Determine the best location to attach the electrode patch and/or electrodes.
3.
Prepare the patient’s skin. If the patient has hair in any of the site, shave it with a safety razor. Use an alco-
hol pad and rub the sites briskly until the skin reddens. For best patch adhesion, allow the skin air dry
before proceeding.
