GE MAC 5500 Resting ECG System Overview
The GE MAC 5500 is GE’s flagship resting ECG system, built on proven innovation in ECG acquisition and analysis, widely used in hospitals, cardiology practices, and high-volume ECG departments:
▸ Expanded Diagnostic Capabilities: 12-channel, 12-lead resting ECG with optional simultaneous 15-lead acquisition for comprehensive ST-segment assessment.
▸ Gold-Standard Interpretation: Powered by the industry-standard Marquette 12SL analysis program for both adult and pediatric ECG interpretation.
▸ Refurbished Efficiency: Tested and certified by AIM Cardio to deliver advanced diagnostic performance and connectivity at a budget-friendly price point.
Clinical & Analysis Features
Engineered to enhance diagnostic accuracy, reduce noise artifacts, and accelerate critical patient triage:
Marquette 12SL Analysis: Delivers documented 12-lead analysis using gender- and age-specific criteria to improve detection of acute myocardial infarction.
ACI-TIPI Chest Pain Triage Option: Combines age, gender, chief complaint, and ECG parameters to compute a numerical probability score for acute cardiac ischemia.
Simultaneous 15-Lead Acquisition: Provides additional ST-segment measurements to evaluate right ventricular and posterior myocardial infarction.
Advanced Arrhythmia Assessment: Offers optional P-Wave Signal Averaging for atrial arrhythmia evaluation and Hi-Res Late Potential Analysis for ventricular risk assessment.
Hookup Advisor & CAM-14 Module: Signal quality programs review waveforms to correct noise interference prior to recording, supported by the digital CAM-14 module.
