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 wavefo
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
