The MAC VU360 employs the same fundamental scientific technology, basic design, construction, materials, energy source, control mechanism, operating principles as the predicate device ELI 380 and the MAC 550 HD in acquiring, analyzing, recording, displaying and printing ECG data for both adult and pediatric populations. The MAC VU360 utilizes the 12SL Algorithm as does the MAC 5500 HD.The basic system prints 6 or 12 leads of ECG and provides optional transmission and reception of ECG data to and from a central ECG cardiovascular information system.
