PURPOSE:To calculate the accurate value of the number of QRS waves even with respect to an electrocardiogram over a long time by providing a QRS wave confirming part confirming a QRS wave from the electrocardiographic signal stored in an electrocardiographic signal memory part and a time memory storing the generation time of the confirmed QRS wave. CONSTITUTION:A digitalized electrocardiographic signal is stored in an electrocardiographic signal memory part 1 and can be read to each part under the control from a central processing part 11. A QRS wave confirming part 4 confirms a QRS wave relatively easy to discriminate from the electrocardiographic signal of the memory part 1 to perform discrimination from other P-wave, T-wave or the like and various noises of an electromyogram or an artifact. A QRS wave generation time memory part 5 calculates the generation time of the QRS wave confirmed by the confirming part 4 to store the same and a QRS wave known generation time presetting part 6 presets the generation time of the QRS wave manually with respect to the electrocardiographic signal of the memory part 1. A confirmation accuracy comparing and counting means 7 compares the data stored in the memory part 5 with the accurate data stored in the preset part 6 and counts the number of excessive reading and reading omission at every certain time unit and totalizes the counting result over the entire time at last over an entire time at last. |
