PROBLEM TO BE SOLVED: To simplify operation and to exactly check the health of the heart even without dedicated knowledge by comparing standard data preserved on a memory with electrocardiogram waveform data and giving warning from an alarm when the difference of both the data exceeds an allowable range. SOLUTION: An electric signal fetched by an electrode piece 1 is amplified by a signal amplifier 11, converted to a digital signal by an A/D converter 12 and inputted to an arithmetic processor 13. The arithmetic processor 13 applies arithmetic processing to the signal, generates electrocardiographic waveform data, supplies these data to a display and outputs them to a comparator 15 together. The comparator 15 compares the electrocardiogram waveform data supplied from the arithmetic processor 13 with the passage of time with the standard data stored and preserved on a memory 17 and outputs the difference to a discriminator 18. By judging whether the difference of both the data exceeds the fixed allowable range or not, the discriminator 18 discriminates the presence/absence of abnormality and when abnormality is discriminated, abnormal information is outputted to an alarm buzzer 19a and an alarm lamp 19b. |
