ARRHYTHMIA MONITORING METHOD AND ARRHYTHMIA MONITORING DEVICE FOR SOUND CARD CAPABLE OF STORING ELECTROCARDIOGRAPH SIGNALS IN DIGITAL RECORDER

摘要

PURPOSE: An arrhythmia monitoring method and an arrhythmia monitoring device are provided to store electrocardiograph signals in a digital recorder by using a single amplifier. CONSTITUTION: An arrhythmia monitoring device comprises a hardware unit including an amplifier for amplifying action potential of heart into electrical signals; and a software unit for inputting the signal to a sound card and reproducing the signal in a computer. The hardware unit includes a surface electrode(10a) having a positive electrode, a negative electrode, and a ground electrode; a single amplifier(18); a stabilizing power supply(19) for supplying power to the amplifier; a low pass filter(20); a signal output terminal(21); a connector(14a); and a microphone input terminal(15a). The input electrocardiography signal is displayed on a display(17a) by an interpretation program, and arrhythmia is monitored.
