  • Patent number: 5410473
    Abstract: A method and apparatus for recording electrocardiogram information, in which ST deviation can readily be visualized and ischemia can be diagnosed with ease at the same time. Compressed recorded waveforms of electrocardiogram waveforms are partitioned and recorded as compressed waveforms of a plurality of lines in a first recording area of a recording paper for recording electrocardiogram information. A predetermined number of lines of the recorded compressed electrocardiogram waveforms in the first recording area are selected in a second recording area neighboring the first recording area, the selected waveforms are superimposed in synchronism with a predetermined characteristic point of the selected waveforms, and the waveforms are recorded while changing location in the area neighboring the predetermined lines of the first recording area.

  • Patent number: 4896677
    Abstract: An electrocardiographic waveform recorder, analyzer, printer and display for superimposing in synchronization, for a predetermined period of time, ECG waveforms. The waveforms are superimposed and synchronized with a predetermined characteristic ECG point (the R-wave peak point) and a plural number of waveforms are expressed while the superimposed positions, at which they are expressed, is changed at fixed intervals of the waveforms, permitting state of deviation recognition.In addition, an ST trend graph and a heart rate output are used for comparisons with environmental conditions. Also, data is recorded continuously over time and displayed and printed at intervals corresponding to the occurrence of the characteristic point of the waveform which permits change in the superimposed waveform display positions. A P wave, a T wave and a QRS wave can be extracted, along with their crest values and the crest value at an arbitrary position in an ST region.
