Apparatus for measuring biological signal

A method for displaying a plurality of biological signals, said method comprising the steps of:

• reading waveforms indicative of said biological signals into a memory;
• setting a marker line display position for a marker line, by synchronizing said marker line with one of said biological signals;
• automatically locating at least one predetermined feature of at least one of said waveforms by forming a detecting point;
• reading a memory address of said detecting point;
• converting said memory address into a display address in a waveform display memory;
• generating a marker signal from said marker line display position;
• composing a display of said biological signals and said marker line based on said waveforms, said display address and said marker signal;
• and
• continuously displaying said display such that said marker line is displayed relative to a time axis of at least one of said biological signals.

An apparatus for measuring biological signals, comprising:

• an input means for receiving and amplifying a plurality of biological signal waveforms;
• a memory means for storing said plurality of amplified biological signal waveforms input through said input means;
• a recognizing means for detecting at least one predetermined feature of at least one of said amplified biological signal waveforms and outputting a detected feature signal;
• a marker line synchronizing position setting means for setting a marker position based on said detected feature signal;
• a marker line generating means for generating a marker line at said marker position set by said marker line synchronizing position setting means;
• and
• a display means for displaying said plurality of biological signal waveforms and displaying said marker line generated by said marker line generating means, whereby said marker line orthogonally intersects a time axis of said plurality of biological signal waveforms.

An apparatus for displaying biological signals, comprising:

• a signal input designed to receive and digitize a plurality of contemporaneous biological signal waveforms, and to output digitized waveform signals;
• a selection input which receives and processes at least one marker line position selection and outputs a setting signal;
• a memory, coupled with said signal input, which stores the digitized waveform signals;
• a waveform recognition processor coupled with said memory and designed to locate at least one predetermined feature of the biological signal waveforms by processing the digitized waveform signals and outputting at least one feature output;
• a marker line position processor, coupled to said waveform recognition processor and said selection input, which receives the at least one feature output, receives the setting signal and generates marker line data based on the at least one feature output and the setting signal;
• a display unit, coupled with said memory and said marker line position processor, which generates and displays a composite signal and marker data based on the digitized waveform signals and the marker line data.
