Stress Testing
3. Enter patient data as described in “Entering Patient Information” on page 57 .
4. Adjust the stress options as necessary:
This includes the speed and gain, finite residual filter, pacemaker enhancement,
printer leads, test protocol, report format, and target heart rate. For more
information on setting these options, see
“Stress Options” on page 98 .
5. Record a preliminary ECG.
This may be a seated, standing, supine, or hyperventilating ECG, depending on
the requirements of the selected protocol.
6. Begin the pretest phase.
a. Have the patient get on the device.
b. Press the Pretest key.
c. Allow the patient to warm up before beginning the exercise phase of the
test.
NOTE:
On supported treadmills, press Start TM to start the belt.
7. When the patient is ready to begin the stress test, press the Exercise key.
During the test, you can use the stress keys to hold the current stage, enter
blood pressure, add a comment, change the displayed leads, and toggle the
finite residual filter. With supported equipment, you can also use the stress keys
to adjust the equipment’s speed, grade, or load. With unsupported equipment,
the equipment must be adjusted manually at the equipment itself.
For more information on making these adjustments, see “Stress Test Keys” on
page 98 .
8. When the exercise phase is complete, press the Recovery key to begin the
recovery phase of the test.
NOTE:
When using an ergometer with remote start, you do not need to press the
Recovery key because the recovery phase begins automatically at the end
of the last stage. However, you can press the Recovery key to begin the
recovery phase before the last stage ends.
On supported treadmills, the belt begins to slow and the grade drops to 0%. On
supported ergometers, the load begins to lighten. On unsupported treadmills
and ergometers, these adjustments must be made manually.
Continue to monitor the patient and record the ECG until the device stops.
9. When the recovery phase is over, press the Test End key.
The menu options at the bottom of the screen change to Confirm Test End and
Continue Test . Do one of the following:
• To return to the test, press Continue Test .
The previous menu options return. Continue to record the ECG as needed.
When you are done, repeat this step.
• To stop the test, press Confirm Test End .
