Quality Assurance


Max1 Stress TestThe Marquette MAX-1 is an interpretive stress test system. This unit has been tested and reconditioned by certified tech. It is patient ready and can ship tomorrow!

NOTE: Treadmill was being processed by our techs when these pics were taken, but it is included with this purchase.





  • Interpretive stress test with treadmill    
  • Patient cables digitizes the signal at the patient, eliminating analog cable noise 
  • Contacts resist corrosion and ensure optimal signal quality
  • Median update helps assure all measurements, including ST segments, are made upon true morphology
  • Technician friendly interface
    • Select standard or customized protocols
    • Intuitive menu design eliminates the need to navigate through multiple layered menus. 
  • Cubic spline baseline correction removes baseline wander without the use of distorting filters
  • TRIM KNOB® control eliminates multiple keystroke functions. 
  • Incremental updating is a beat to beat process that illustrates ST changes for real-time decision making.
