Specific embodiment

Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are the schematic diagram of simplification only with signal side Formula illustrates the basic structure of the present invention, and therefore it only shows the composition relevant with the present invention.

New cardioelectric monitor service system as shown in Figures 1 to 3, have ECG detecting terminal 1, cordless communication network 2 with And hospital monitoring center 3, ECG detecting terminal 1 is connected with cordless communication network 2, cordless communication network 2 pass through wireless network with Hospital monitoring center 3 connects, and described ECG detecting terminal 1 includes ecg signal acquiring module 4, and ecg signal acquiring module 4 will Data sends single-chip microcomputer 6 to by analog-to-digital conversion module 5；

Described cordless communication network 2 includes gprs wireless transport module 7 and pc machine 8, and described single-chip microcomputer 6 is wirelessly transferred with gprs Module 7 and pc machine 8 connect, and gprs wireless transport module 7 is connected with sim card 9.

Ecg signal acquiring module 4 includes electrocardioelectrode module 13, and electrocardioelectrode module 13 passes through pre-amplifying module 10 are connected with low high-pass filtering module 11, low high-pass filtering module 11 and 50hz trap module 12 pass through photoelectric isolation module 14 with Rear class is amplified and level lifting module 15 connects.
