PROBLEM TO BE SOLVED: To provide an electrocardiograph for issuing alarm to give notification to a diagnosed person when a contact defect occurs or a battery voltage to drive the electrocardiograph is at a level equal to or less than a prescribed one concerning the electrocardiograph for measuring electrocardiographic waveforms by winding a belt around the breast of the diagnosed person and pressurizing electrodes against the breast.SOLUTION: The electrocardiograph 1 performs measurement so as to transmit electrocardiographic waveform data to a computer 2. When the computer 2 determines that the waveforms are normal, an indication is issued to record the effect in a storage medium 7 attached to the electrocardiograph 1. When the waveforms are not normal, a vibration motor 9 for giving a vibration to the breast is driven. When the battery voltage is equal to or less than the prescribed voltage during recording in the storage medium 7, the alarm is issued with the use of a red LED 5R. When the voltage is further lowered, the vibration motor 9 is driven to give the notification to the diagnosed person.COPYRIGHT: (C)2012,JPO&INPIT【課題】被診断者の胸にベルトを巻き回し電極を胸に押し付けて心電波形を測定する心電計において、接触不良または心電計を駆動する電池電圧が所定のレベル以下であった場合に警告して被診断者に知らせることのできる心電計を提供すること。【解決手段】心電計1で測定して心電波形データをコンピュータ2に送信してその波形が正常であるとコンピュータ2が判断したときに心電計1に取付けられた記憶媒体7に記録するように指示し、正常でないときは胸に振動を与える振動モータ9を駆動し、また記憶媒体7に記録中に電池電圧が所定電圧以下のときは赤LED5Rで警告するが、更に低下したときは前記振動モータ9を駆動して被診断者にしらせるようにした。【選択図】図1
