ABSTRACT:
An object of the present invention is to provide an apparatus for measuring biological signals, which is capable of displaying marker lines on a time axis in synchronism with a particular position of a reference wave so that, if an electrocardiogram is selected as the reference wave, a plurality of other biological signals can be monitored in comparison with the electrocardiogram. According to the present invention, an apparatus for measuring biological signals includes an input unit for simultaneously receiving and amplifying a plurality of biological signal waveforms; a memory device for storing the plurality of biological signal waveforms input through the input device; a marker line synchronizing position setting device for determining a marker position by setting an arbitrary position of at least a single biological signal waveform that serves as a reference signal selected from the plurality of biological signal waveforms stored in the memory device; a marker line generating device for generating a marker line at the position set by the marker line synchronizing position setting device; and a display device for displaying the plurality of biological signal waveforms stored in the memory device and displaying the marker line generated by the marker line generating device such that it intersects the time axis of the plurality of biological signal waveforms orthogonally.
