In 1976, the Naval Submarine Medical Research Laboratory NSMRL, Groton, Connecticut, initiated the development of an interactive, computer-based medical diagnosticinformation system MEDIC that would serve as a medical consultant to the Independent Duty Corpsman. The system was designed for use on submarines where such common tools as x-rays and electrocardiograms ECGs are not available. During the development of the Navys chest pain diagnostic program. it became clear that ECG data would Improve the accuracy of diagnosis of a myocardial event and improve the corpsmans ability to treat such patients. Existing ECG recorders were too large to be used aboard submarines and lacked transmission capability. After evaluating many ECG systems, Marquette Electronics, the supplier of the MAC-II ECG recorder being used as part of the Tri-Service Medical Information Systems TRIMIS Computer Assisted Processing of Cardiograms CAPOC program, was asked to develop a small portable ECG machine that could provide data for input to the MEDIC system. To meet this requirement, Marquette extensively redesigned their standard MAC-II recorder, and in November 1985 delivered a 12 x 8 x 4 inch recorder that weighed just under 12 pounds. The recorder can record on 12 channels, is battery operated, prints ECG tracings with full diagnostic interpretation, can transmit the tracings to the CAPOC system through a modem, and can store up to 50 ECG tracings. Feedback from the submarine community has been favorable. In addition to its intended uses by the Navy, the MAC-PC can be used in such places as ambulances, emergency medical vehicles, and physicians offices.
