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. A T-wave peak may serve as a characteristic time point value. Outputs can be the P-wave trend graph and the P wave, along with the trend graph of the QRS-wave peak and the QRS wave and a trend graph of the T-wave peak and the T wave all possibly displayed on the same time axis, in the same time interval display region.
