The Q 3000 stress console controls the treadmill speed and grade by means of the selected protocol and displays
speed and grade information in the numeric display.
ECG data is collected from electrode sites on the body.
Computes heart rate, ST parameters, and other information.
Hardcopy print of ECG and computed information.

Overall System
Frequency response: 0.05 to 100 Hz (+1,-3dB) for chart recorder. Fixed gain control: 5,10,and 20 mm/mV. Filters: 25 Hz, 4-pole, low pass artifact filter for the screen and a 25 Hz, low pass digital filter for the chart recorder; key selectable. Overall signal error: for a ±0.5 to ±5.0 mV signal, error is less than ±10% or 50 µV, whichever is greater. Input impedance: 10 megohms minimum. Common mode rejection: 100 dB at 60 Hz. Power requirements: 90-132 VAC, 45/450 Hz, 500VA; 180-264 VAC, 45/450 Hz, 500VA; 250-375 VDC, 350 W. Dimensions: 21.2″ x 62.3″ x 30.5″ (53.8 x 158.2 x 77.5 cm) WxHxD. Weight: 300 lbs (136 kg)

Screen Description
Displays 3 channels of ECG waveforms plus alphanumeric information for identification and labelling purposes, calculated parameters, and messages to the operator. Size: 9×7 inches (23x18cm) WxH. Sweep speed: 25 mm/sec. Memory span: 8 seconds for each channel. HOLD feature: split screen format with oldest 4 seconds of ECG display capable of being frozen. Write from memory: both HOLD and continoues ECG may be written from the CRT memory to the chart recorder with full AHA diagnostic quality.

Chart Recorder
Description: records three 5 mm wide ECG channels and a 45 mm wide half channel containing alphanumeric data for labelling and calculated parameters. Writing method: high-resolution, thermal printhead. Speeds: 5, 25, and 50 mm/sec. Paper capacity: 200 feet (61 m) of z-fold paper. Paper size: 8 ½” x 11″ ( 216 x 280 mm). Papertype: thermal paper, z-fold.

ECG Computations
Calculated parameters: heart rate, ST level, and ST slope. Fiducial point for ST measurement: J- junction.

Description: alphanumeric screen readouts of stage number, stage time, exercise time, and recovery time. Accuracy:±0.1% ±1 second.

ECG Simulator
Outputs are simulated ECG signals for the 14 electrode sites; heart sites; heart rate is 30 to 240 bpm, user selectable through the test and calibration mode.
