To provide an electrocardiographic device capable of performing analysis on the basis of an appropriate electrocardiogram.SOLUTION: Propriety determination means 16 determines whether or not proper measurement has been carried out on the basis of an electrocardiographic waveform upon receipt of an electrocardiographic waveform from electrodes 1, 1 ... Stability propriety determination means 4 calculates a fluctuation amount of a baseline of each beat with regard to an electrocardiographic waveform of a proper beat in a propriety determination section. A stability level is imparted to each proper beat according to the fluctuation amount of the baseline of each beat. Propriety output means 6 outputs an output to the effect of improperness from a propriety output unit 8 if there is no propriety determination section from the start of the measurement to the present time. If there is a propriety determination section, the propriety output means outputs the highest stability level of each propriety determination section from the propriety output unit 8. Referring to the output of the propriety output unit 8, an operator directs the start of an analysis output to start reception means 10. Analysis output means 12 calculates and outputs findings of the Minnesota code, etc. on the basis of an electrocardiographic waveform in the propriety determination section. An average electrocardiographic waveform and its waveform feature amount only by an individual beat of the electrocardiographic waveform in the propriety determination section are calculated and output.SELECTED DRAWING: Figure 1【課題】 適切な心電図に基づいて解析を行うことのできる心電計測装置を提供する。 【解決手段】 適否判断手段１６は、電極１、１・・・からの心電波形を受けて、心電波形に基づいて、適切な計測が行われたかどうかを判断する。安定性適否判断手段４は、適正判断区間の適正拍の心電波形について、各拍の基線の変動量を算出する。各拍の基線の変動量に応じて、各適正拍に安定性のレベルを付与する。適否出力手段６は、計測開始から現在までに、適正判断区間がなければ不適切の旨の出力を適否出力部８から出力する。また、適正判断区間がある場合、各適正判断区間のうち最も高い安定性のレベルを適否出力部８から出力する。操作者は、この適否出力部８の出力を参照して、開始受付手段１０に解析出力の開始を指令する。解析出力手段１２は、当該適正判断区間の心電波形に基づいてミネソタコードなどの所見を算出して出力する。適正判断区間
