Cost-effective Electrocardiography
The MAC 500 resting ECG system is a portable twelve lead electrocardiograph, designed for acquisition, with or without analysis. The system can be configured as a very basic electrocardiograph without analysis for those facilities needing minimal ECG requirements-or be configured to incorporate the proven Marquette 12SLTM ECG analysis program. By adding the 12SL program into the system you will create an electrocardiograph with the best "second opinion" analysis and measurements program available. If your facility would only…
Cost-effective Electrocardiography
The MAC 500 resting ECG system is a portable twelve lead electrocardiograph, designed for acquisition, with or without analysis. The system can be configured as a very basic electrocardiograph without analysis for those facilities needing minimal ECG requirements-or be configured to incorporate the proven Marquette 12SLTM ECG analysis program. By adding the 12SL program into the system you will create an electrocardiograph with the best "second opinion" analysis and measurements program available. If your facility would only require measurements, we offer a version which includes 12SL measurements only. Whatever the situation, the MAC 500 resting ECG system most certainly can be a very cost-effective addition to compliment your resting ECG requirements.
