title: [Research on metrological verification and the development of the verification equipment for digital electrocardiographs].
abstract: In order to guarantee that digital electrocardiographs with an adequate accuracy and reliabity are available for measurements in clinical practice, it is very important to determine the metrological characteristics, methods and to develop the equipments for verification. This paper elaborates the basic functions, specification, schematic drawing and key techniques of calibration equipments as well as test items for digital electrocardiographs.
