PURPOSE:To make it possible to perform rapidly retrieval of abnormal wave shapes such as cardiac dysrhythmla and to improve efficiency of diagnosis by providing a memory device for data of a measured electrocardiogram, a display device, a retrieval device retrieving QRS of a wave shape and a display controlling device. CONSTITUTION:If QRS is normal, time difference between QRSs t(n)-t(n+9) is approximately a const. interval but on an abnormal QRS 20 such as cardiac dysrhythmia, an extremely short interval as shown in t(i) is exhibited. In the retrieval device, while QRS groups are successively detected from data of electrocardiogram stored in IC cards 3, QRS intervals t(n) are operated and for example, when 8 t(n) are accumulated, the average value ta is operated and calculated and the average value ta is compared with the next QRS interval and when it is extremely shoter than the average value ta, it is judged to be an abnormal QRS. Then, data of electrocardiogram recorded in the IC card are reproduced and the wave shapes are displayed on LCD 7. |
