GE MAC 3500 EKG Machine Features

The GE MAC 3500 EKG Machine will increase productivity and improve analysis with one of the hardest-working, affordable resting ECG systems in the industry.

  • Increase productivity with its common interface and intuitive operation
  • Improve the sensitivity of emergency physicians’ interpretation of acute myocardial infarction by 50% and cardiologists’ interpretations by 26%, with no loss of specificity1 with its Acute Coronary Syndrome (ACS) Algorithm. The new ACS algorithm also improved the emergency physician’s acute ischemic syndrome interpretation sensitivity by 53%, while maintaining a specificity of 91%1
  • Speed triage and time to treatment for patients at high risk of cardiac events with configurable critical values and onscreen and printed notifications
  • Tap into the power of MUSE™ Cardiology Information System for streamlined workflow and higher functionality with our optional communications package with wireless, LAN, or modem selections
  • Reduce patient data entry time and errors with an optional automated process that includes barcode readers
  • Support your facility’s patient safety goals and the Joint Commission’s reporting requirements through consistent reporting of critical conditions
  • Easy to read color screen displays 12 leads at a time.
  • Marquette 12SL ECG simultaneous 12-lead ECG analysis program for adults and pediatrics.
  • 12SL with Gender-Specific interpretation makes detecting AMI in women easier.
  • Marquette Hook-up Advisor signal quality analysis program reduces poor waveform quality during ECG recording.
