Exercise Stress Testing
• Press the emergency stop button (usually mounted on the treadmill) to stop
the treadmill IMMEDIATELY.
• Press the Speed W + , Speed W – , and Grade keys to manually control the
test. However, once you press these keys, the pre-programmed protocol
becomes inactive: you must manually control the speed and grade during
the remainder of the exercise and recovery phases.
The following menu items are available during the pretest phase of the exercise test:
Menu Item Description
Patient Data Enter a patient’s name, ID number, and so forth. Enter the
patient’s age to allow your system to calculate the maximum
and target heart rates.
New Protocol Select a different exercise test protocol. This function is only
available if the test will be printed only (not stored to memory).
Measurements
Reestablish the median complex, set the J point, and select the
three leads used to calculate heart rate.
Leads Select the leads used for 3 or 6 Rhythm leads, All Leads, Lead
Check, or Lead Placement.
Median Select a lead to act as the median lead. This can be a fixed lead
or scanned for lead with most ST depression.
Writer
Change the writer’s arrhythmia documentation (doc.), cubic
spline (baseline control), paper speed, gain, filter, and writer
on/off settings.
Exercise Phase
The selected protocol controls the treadmill or ergometer. When you enter the
exercise phase:
• the belt speed and grade or the ergometer workload changes according to the
selected protocol,
