Abstract
An electrocardiograph has an R wave detector for detecting an R wave out of an electrocardiogram (ECG) signal being collected from a subject. When the R wave detector detects an R wave, a heart rate and an ST value of the ECG signal are written to a storage which is assigned to heart rates and ST values in synchronism with the R wave. When the subject presses an event switch on feeling a subjective symptom, the waveform of the ECG signal is written to another storage which is assigned to waveforms. The electrocardiograph records a minimum necessary amount of information for screening, i.e., the heart rates, ST values, and waveforms of ECG signal associated with subjective symptoms. The electrocardiograph is, therefore, miniature and easy to carry while reducing the period of time necessary for analysis.
