What is it indicated for?
The Q-Stress Echo™ Bed is intended for use in stress echocardiography examination. The Q-Stress Echo™ Bed provides an exercise source that delivers programmable, controlled variable resistance.
The Q-Stress Echo™ Bed incorporates an electrocardiograph that records either normal conditions or patterns of arrhythmia and/or rate abnormalities in patients. In addition, the stress echo workstation provides “QRS” complex to a cardiac ultrasound device to be used to capture images (heart beats), either digitally or on videotape, such that each image begins at the time systole begins.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
