PURPOSE:To accurately record an electrocardiographic wave form judged to be abnormal from the aspect of electrocardiographic wave form analysis over a long time, by comparing the detected electrocardiographic wave form with the common wave form of a Minnesota cord to store only the electrocardiographic wave form shifted from said common wave form. CONSTITUTION:An MPU 11 inputs the digital signals outputted to a common bus 12 from A/D converters 17, 20 and successively stores the same in the prede termined address of an RAM or compares the same with the common wave form of a Minnesota cord to store only the electrocardiographic wave form shifted from the 'common wave form' in the RAM 14. The MPU 11 confirms whether 24hr is elapsed and, when 24hr is not yet elapsed, said MPU 11 again performs the input and storing of an electrocardiographic wave form. This repeated processing is continuously performed for 24hr. Further, the MPU 11 reads the electrocardiographic wave form data already recorded on the RAM 14 by the arrival of an interruption signal and successively outputs the same to a large-scale computer through an output port circuit 22 and an output connec tor 23. |
