GE MAC 5500 HD ECG System

The MAC 5500 represents the innovation of GE in healthcare as it is one of the most advanced machines for disease management apparatus. The machine provides sophisticated solutions for non-invasive diagnosis and testing. It uses advanced algorithms for effective and accurate ECG interpretation and graph analysis.

With usage cases in a wide range of applications including both children and adults, it is certified
to operate in a vast number of environments. It covers the following analysis algorithms under its
system to provide extensive diagnostic capabilities:
– Marquette 12SL* ECG analysis program for adults and pediatrics
– Marquette Hookup Advisor* signal quality analysis program
– Marquette 12SL with Gender-Specific interpretation
– ACS (Acute Coronary Syndrome)
– Marquette 12SL with ACI-TIPI (Acute Cardiac Ischemia Time-Insensitive Predictive
– Simultaneous 15-lead acquisition, storage, and assessment
– P-Wave Signal Averaging
– Hi-Res Late Potential Analysis
– High Definition Pacemaker-Detection Software
– Serial ECG Comparisons using MUSE


The machine is easy to operate and allows for fast and streamline workflows to minimize
individual ECG generation times. Some key features offered in this machine include the
– Clearer image with minimal noise using the Digital CAM-HD module.
– Analog outputs allow plugging into other diagnostic tools for cardiac function.
– Patient data automation with the option for barcode scanning to automate date retrieval and

– Advance security features for ensuring adherence to HIPAA concerns and end to end data
– Compact design with trolley feature for maximum mobility
– Stress option for exercise testing with minimal distortion using better signal-acquisition for
much more accurate ECG results.
Major processing features along with their specifications are provided below:
