In medicine, as in politics, weedkillers or any other context, means "extending throughout". The system is singular and the whole.
The use of "a system" is quite different, implying one of several. When several systems are affected the term is multi-system. Moreover in medicine multsystem is used, not for symptoms in lots systems but for pathology in multiple systems. It is even narrower than that because slthough dilated cardiomyoathy leads to pathology in liver, lung, kidney and elsewhere it would not be considered multisystem because the primary pathology is clearly in one place.
MECFS is the opposite of multisystem because we have not found pathology anywhere.
