Marquette MAC 500

The MAC 5000 is Marquette's premier resting ECG system. It delivers the advanced disease management capabilities that only the industry's most extensive collection of proven algorithms can offer. The MAC 5000 system provides the sophistication required for advanced ECG applications, while its ease of use extends this degree of performance to the broadest range of users possible.

Advanced algorithm capabilities include true, 12-lead ECG computer analysis and interpretation, P-wave signal averaging, late potential analysis and 15-lead ECG analysis - for effective management of ventricular arrhythmia, atrial arrhythmia and chest pain.

The MAC 5000 system uniquely delivers seamless connectivity to the MUSE CV® Information System for data storage and retrieval of ECGs.

Combine this connectivity with the inherent performance of the MAC 5000 system and you've got the ultimate resting ECG system.
