PURPOSE:To enable the diagnosing or the like of ST waves and QRS waves especially vital in electrocardiography by a method wherein an electrocardiographic complex is recorded at reference sensitivity and subsequently, one heart beat alone is recorded at the sensitivity half as much as the reference sensitivity again without duplication or the like in the electrocardiographic complex with the frame of a recording paper trimmed in the recording at the reference sensitivity. CONSTITUTION:When electrocardiogram information during a measurement is printed and recorded with a recording section, 2 recording key of a keyboard 11 is depressed to input. Detecting the depression of the recording key through a keyboard control circuit 9, a main CPU1 starts a recording control 20 and a member induction of an electrocardiographic complex measured is printed and outputted from the recording section 21. At the recording section 21, firstly, I-III induction is printed and recorded by a specified number of heart beats. Checking is performed to see whether the electrocardiographic complex measured as recorded is within a recording area of the recording section 21. When it is not within the recording area, the electrocardiographic complex is reduced so that it is held within the recording area and the printing and recording is performed following the preceding record. For example, the recording is performed at sensitivity half as much as the preceding reference sensitivity. |
