1. Getting startedRefer to the HR100/HR300/HR1200 Instructions For Use for detailed information on the HR300Holter Recorder.2. Recording a mini Holter Event ECG testThe Welch Allyn Mini Holter Event ECG System easily records ambulatory ECG tests. Use thetwo channel retrospective mode.Memory CardThe removable Memory Card stores up to 90 minutes of two channel data recordings.Retrospective modeYou can use retrospective mode if:• the patient has rather frequent symptoms.• you want to record the onset of an event.Monitoring can last from a few days up to a few weeks. You can freely adjust the amount of ECGrecorded before and after activation. It is only limited by the capacity of the Memory Card that isused.In a retrospective test the patient wears the recorder for a certain period. The recorder isconnected to the patient with special long term electrodes. It continuously records ECG into aloop of memory until the patient feels an irregularity in his heartbeat and chooses to make arecording. When the patient activates the recorder by pressing the button, ECG is stored fromboth before and after activation.Retrospective testsThe HR300 Holter Recorder does not support Recordings at specific times.Retrospective mode is commonly used to record two channels of ECG, enabling betterdiscrimination of cardiac rhythm and conduction.Mat. 711232, Ver A 4

2.1 Recording a retrospective testTo record a test in retrospective mode, you need to follow these global steps. Steps 2, 3, 4, 6and 7 are explained in more detail on the following pages.1) Place the memory card in the card reader that is connected to your computer.2) Select a patient or create a new one.3) Create a new test.Note: If the patient's symptoms require a large series of recordings, you can supply himwith more than one Memory Card. You then need to store the test settings on all cards,which means that you have to create the same test more than once, each time with anew card in the card reader.4) Prepare the recorder before connecting it to the patient.5) Place the Memory Card in the recorder (note the arrow). Push the card fully in.6) Connect the recorder to the patient.7) Start the recorder.8) The patient carries the recorder with him for some time. To ensure that the recorder willrecord properly, you may need to give the patient a sheet with a few instructions (See theappendix; you can make a copy of it).9) When the patient returns, place the Memory Card in the card reader again and read backthe recordings.Mat. 711232, Ver A 5

Create a new retrospective testBefore you can record a retrospective test, you first need to create a new test. The test settingsare stored on the Memory Card that you put in the card reader that is connected to yourcomputer.Note: If the patient's symptoms require a large series of recordings, you can supply him with twoMemory Cards. You then need to store the test settings on two cards, which means that you haveto create the same test twice.To create a new retrospective test::1. In the File menu, point to New and click Recollect test. The New Recollect Test dialogbox is displayed.2. Select the physician that ordered the test and a specialty. Click Next. The Recording tabis displayed.Note: The card capacity value is 2 times the actual recording time3. Select Retrospective Mode as recorder mode.Mat. 711232, Ver A 6

4. Select Two Channels.5. Set the ECG Recording Times. The Possible Recordings field shows how manyrecordings of the selected duration can be stored on the Memory Card and the Utilizationfield shows how much of the card capacity will be used.6. Click OK. The test settings are now stored on the Memory Card.Set ECG recording timesWhen you create a retrospective Event ECG test, you need to set these ECG recording times.You can do this in the New Recollect Test dialog box.1) In the Recording Duration field, enter the total time ECG is stored when the patientmakes a recording. You can enter the time value in two ways: the number of seconds orthe number of minutes.Example:The total recording duration is one minute.If you want to enter the value in... Type...seconds 60minutes 1:002) In the Pre-Trigger Time field, enter the time ECG is stored before the patient presses therecord button. You can also set the pre- and post-trigger time by using the slide bar.Note: The total amount of time before and after the button press always equals the totalrecording duration. When you have entered the pre-trigger time, the post-trigger time isautomatically determined.Save test settingsAfter setting the test settings, you can save them. The settings are saved on your computer, sothat you can use them again for another test.To save the test settings:1) In the New Recollect Test dialog box, click the Save As button.
