Twelve lead-twelve track type event-driven ambulatory electrocardiograph for cardiac activity monitoring system, has digital-to-analog converter redirecting converted analog signal to plug compatible with connector of wire

摘要

The electrocardiograph (200) has arms equipped with dry precordial electrodes. An analog-to-digital converter (315) converts an analog signal acquired by the electrode into a digital signal. A rewritable non volatile memory (314) stores the digital signal. A digital-to-analog converter (325) converts the digital signal into analog signal and redirects the analog signal to a plug compatible with a connector (311) of a wire (312). Another connector of the wire is compatible with another electrocardiograph (300).
