The Exercis Test is an in-office only test. To access from the Quick Look™ II screen, select Tests -> Exercise

• If Rate Profile Optimization (RPO) is programmed to Off, the Rate-Response parameters remain set to their programmed values
• When RPO is programmed to On, this feature adjusts the Rate-Response parameters once each day

• Lower Rate (LR) Setpoint determines the activity counts required to pace at a rate higher than the lower rate
• ADL Setpoint determines the minimum sensor response to pace at the ADL Rate (i.e., the approximate target rate that the patient’s heart rate is expected to reach during activities of daily living)
• Upper Rate (UR) Setpoint determines the minimum sensor response to pace at the Upper Sensor Rate, which is at the upper limit of the exertion rate range

1. Select the Duration field on the Exercise Test screen and set the value for the test duration (5 or 20 min).
2. Select the Vector field and set the value from the list shown. Press [PROGRAM] to program the Vector value selected for the test. Note: Do not change the currently programmed values for LR Setpoint, ADL Setpoint, and UR Setpoint before conducting the exercise test. These values may serve as the baseline to determine whether it is necessary to adjust the rate-response setpoints for the patient, depending on the test results.
3. Press [START] to start the test. A message window (see below) with a warning appears on the screen that starting another exercise test will overwrite the current test results.
4. Select [Continue] (see below) to initiate the test in the device or [Cancel] to return to the Exercise Test screen without starting the test.
5. Once you select [Continue], remove the programming head from the device and instruct the patient on the type of activity to perform, such as hall walk or treadmill walk. During the test, have the patient perform activities that require progressively higher levels of exertion, such as sitting, walking, and vigorous exercise. While the exercise test is in progress, observe the patient’s activity. If the patient is instructed to perform different activities, observe the duration of each.

For each Exercise Test, the device collects and stores the following information, which is displayed on the Exercise Test screen:

• Start time for the test
• Programmed activity vector - the activity vector that was selected/programmed as appropriate for the patient’s activity levels
• Exercise Test duration
• Activity count data - The activity counts used to calculate the sensor rate are based on the frequency and amplitude of the accelerometer signal
• Heart rate data
• Sensor rate data - this is the pacing rate data

1. When the Test Complete message appears on the Exercise Test screen, reposition the programming head over the patient’s device.
2. Press [Stop and Retrieve] to collect the test data. The test data is displayed as the Activity Counts graph on the Exercise Test screen.
