Electrocardiographic system with a communication device

摘要

An electrocardiographic system comprising an electrocardiograph transmitting the produced cardiograms and a communication device wirelessly communicating with the electrocardiograph. The communication device accepts a subject's posture selected from multiple posture options, and transmits a specific instruction signal to the electrocardiograph upon receiving the selection. The electrocardiograph stores a cardiogram produced when the instruction signal is received from the communication device as a reference cardiogram corresponding to the selected posture discriminating it from other cardiograms.
