PROBLEM TO BE SOLVED: To enable the efficient data compression transmission of electrocardiodata without delay by determining the differential signals among a plurality of electrocardiogram signals and transmitting the differential signals subjected compression processing with a multiinduction electrocardiogram transmitter which simultaneously radio transmits the plurality of induction electrocardiogarams. SOLUTION: Respective electrodes 1 exclusive of an RA electrode are connected to the input of a differential amplifier 2 which makes the output from an LF electrode as a reference for the difference. II and III inductions are derived from limbs electrodes and the deviations of the respective electrodes 1 based on LF are derived from chest part electrodes. The II and III induction data digitalized by an A/D converter 3 are inputted as they are to an encoding section 4. On the other hand, the induction data from the chest part electrodes are permutated only to the electrodes normally mounted in accordance with the electrode abnormality detection information from an electrode abnormality detection section 7 and are inputted to a subtractor 6. The encoded data are processed by a transmission backet synthesizing section 8 and a modulating section 9 and after radio signal are subjected to modification, the signals are transmitted from an antenna 10. |
